Strelec WinPE, commonly called Sergei Strelec WinPE, is a bootable computer maintenance, recovery, diagnostic and deployment environment assembled and maintained by Sergei Strelec.

It is based on Microsoft Windows PE (Windows Preinstallation Environment) but extends the basic WinPE environment with a graphical desktop, drivers, boot managers and a large collection of utilities used by computer technicians, system administrators, data-recovery specialists and advanced users.

The important distinction is:

Microsoft develops Windows PE. Sergei Strelec did not invent Windows PE itself.

Rather, Sergei Strelec created and maintains the Strelec WinPE distribution/toolkit built around Windows PE, integrating many maintenance and recovery applications into a bootable environment.

Microsoft describes Windows PE as a small operating system intended for installing, deploying and repairing Windows. It can prepare disks, install Windows, capture/apply Windows images, modify an offline Windows installation and recover files from computers that cannot boot normally.

The Strelec project takes that underlying technology and turns it into a much broader technician-oriented rescue environment.

Who Created Strelec WinPE?

The project is associated with and maintained by Sergei Strelec, hence names such as:

• Sergei Strelec WinPE
• WinPE Sergei Strelec
• Strelec Boot
• Strelec Rescue Disk
• WinPE 11-10-8 Sergei Strelec

The official project site publishes the builds, descriptions, version history and checksums.

The project has existed for many years. For example, archived official releases show Strelec WinPE 10 builds dating back to at least 2016, while later releases expanded into Windows 8, Windows 10 and Windows 11 PE environments.

As of 2026, the project is still being maintained. The official version history lists 2026 releases with updated recovery, backup, partitioning, diagnostic and remote-access utilities.

What Is Windows PE?

To understand Strelec, first understand Windows PE.

Windows PE stands for:

Windows Preinstallation Environment

It is Microsoft's lightweight Windows environment designed primarily for:

• Windows installation
• Windows deployment
• Windows imaging
• Offline Windows repair
• Disk preparation
• Recovery
• Troubleshooting

Unlike a normal Windows installation, WinPE does not need to be installed permanently on the computer.

It can boot from:

• USB flash drive
• ISO image
• CD/DVD
• PXE/network
• Virtual disk
• local storage

Microsoft confirms that WinPE can operate without a hard disk and can run from RAM.

This capability is one of the fundamental technologies that makes Strelec so useful.

How Does Strelec WinPE Work?

A normal computer might contain:

SSD/HDD → Windows Boot Manager → Windows 10/11 → Applications

Strelec changes the startup path:

USB → BIOS/UEFI → Strelec Bootloader → Windows PE → Recovery/Diagnostic Applications

The installed Windows operating system does not need to start.

This is extremely important.

Suppose Windows is damaged by:

• corrupted registry
• broken bootloader
• damaged EFI partition
• malware
• failed Windows Update
• damaged system files
• incorrect disk conversion
• deleted partitions
• corrupted BCD
• forgotten local password
• failing HDD
• failing SSD

You can boot Strelec independently and examine the computer from outside the installed operating system.

Why Is Strelec WinPE Special?

The main advantage is not merely that it boots Windows PE.

Its strength is the large integrated technician toolkit.

Instead of maintaining separate USB drives for:

• partition recovery
• disk cloning
• imaging
• SMART diagnostics
• file recovery
• boot repair
• password recovery
• Windows installation
• hardware testing

a technician can access many of these categories from one bootable environment.

The current official x64 description, for example, lists utilities for backup/restore, disk management, diagnostics, data recovery and other administrative functions.

Major Categories of Tools Available in Strelec

The exact applications change between releases, so always check the specific version you are using.

Typical categories include:

1. Backup and Disk Imaging

Strelec builds have included tools such as:

• Acronis True Image
• Macrium Reflect
• AOMEI Backupper
• Hasleo Backup Suite
• R-Drive Image
• Drive Snapshot
• TeraByte Image for Windows
• Active Disk Image

These can be useful for:

Disk → Image File

or:

Old SSD → New SSD

or:

Backup Image → Replacement Disk

The 2026 official builds continue to update many of these utilities.

2. Partition Management

Strelec commonly includes multiple partition-management tools.

Examples appearing in current builds include:

• MiniTool Partition Wizard
• AOMEI Partition Assistant
• EaseUS Partition Master
• DiskGenius
• NIUBI Partition Editor
• Active Partition Manager
• Macrorit Partition Expert

These may help with operations such as:

• viewing partitions
• resizing partitions
• copying partitions
• examining GPT/MBR layouts
• recovering lost partitions
• changing drive letters
• examining EFI System Partitions

Be extremely careful when modifying partitions on a disk containing important data.

3. Data Recovery

This is one of the strongest uses of a WinPE rescue environment.

Current Strelec builds include or have included tools such as:

• R-Studio
• GetDataBack
• EaseUS Data Recovery
• Active File Recovery
• Active Partition Recovery
• TestDisk
• DiskGenius

These can help investigate situations such as:

NTFS → RAW

Partition deleted

Windows no longer boots

Files accidentally deleted

Partition table damaged

Drive visible in Disk Management but inaccessible

Because Strelec runs independently from the installed Windows system, it can access disks without booting the damaged Windows installation.

4. HDD and SSD Diagnostics

Strelec includes hardware and storage diagnostic utilities.

Current official descriptions include tools such as:

• Hard Disk Sentinel
• CrystalDiskInfo
• CrystalDiskMark
• HD Tune
• HDDScan
• Victoria
• HWiNFO
• AIDA64
• CPU-Z
• HWMonitor

These can help investigate:

• SMART warnings
• bad sectors
• disk temperature
• SSD health
• HDD health
• storage performance
• hardware identification
• CPU information
• motherboard information
• memory configuration

5. Memory Testing

Some builds include memory-testing utilities such as:

MemTest86

and/or

Memtest86+

The 2026 version history shows UEFI-capable memory testing utilities being maintained in current builds.

This makes the USB useful when troubleshooting:

• random BSODs
• unexplained crashes
• corrupted installations
• installation failures
• memory-related instability

6. Windows Boot Repair

Strelec is particularly useful when Windows itself cannot start.

Technicians can investigate:

• BCD
• EFI System Partition
• Windows Boot Manager
• MBR
• GPT
• boot sector
• Windows partition
• recovery partitions

Native Windows utilities available in WinPE can include technologies such as:

DiskPart

DISM

BCDBoot

Microsoft specifically identifies DiskPart and BCDBoot among WinPE's supported storage technologies.

7. Offline Windows Repair

Because the installed Windows partition can be accessed while Windows itself is offline, administrators can perform advanced troubleshooting without fighting locked files or an unstable OS.

Possible tasks include:

• copying important files
• inspecting Windows folders
• checking partitions
• restoring registry backups
• restoring system images
• replacing damaged files
• repairing boot configuration
• applying Windows images

This is one of the biggest advantages of WinPE.

8. Windows Installation

Strelec is not limited to recovery.

It can also assist with Windows deployment.

Utilities such as WinNTSetup are present in current builds.

A technician can therefore maintain a USB containing Strelec plus Windows installation images and use it for:

• Windows 10 installation
• Windows 11 installation
• Windows Server deployment
• image-based installation
• disk preparation

9. Network Support

WinPE itself supports networking, including TCP/IP and access to network resources.

Strelec extends this into a technician-friendly environment where networking can be useful for:

• copying recovered data to a NAS
• accessing network shares
• transferring files
• remote troubleshooting
• downloading drivers
• accessing another computer

Some Strelec releases also provide facilities for loading additional network/WLAN drivers.

10. Remote Support

Modern Strelec builds may contain remote-access utilities.

For example, the 2026 version history lists applications such as:

• AnyDesk
• RustDesk
• HopToDesk
• TightVNC
• UltraVNC

depending on the particular release.

This can be useful in specialized remote-support scenarios, although network and driver availability must first be established.

Technology Behind Strelec WinPE

Strelec is not a completely independent operating system.

Several technologies work together.

Layer 1 — BIOS or UEFI Firmware

The computer firmware discovers the bootable USB.

Older computers normally use:

Legacy BIOS

Modern computers normally use:

UEFI

Some systems provide:

UEFI + CSM/Legacy compatibility

Layer 2 — Bootloader

The bootloader starts the appropriate PE environment.

Strelec documentation describes both Microsoft's standard EFI loader and an optional GRUB2 configuration for expanded UEFI functionality.

Therefore the startup chain can roughly be:

UEFI → EFI Bootloader → WinPE

or:

Legacy BIOS → Bootloader → WinPE

Layer 3 — Windows PE

The actual mini-Windows environment is loaded.

WinPE supports Win32 applications, drivers, networking, DISM, NTFS, DiskPart, BCDBoot and optional technologies such as PowerShell and BitLocker-related components.

Layer 4 — WIM/RAM Disk

WinPE commonly boots from a Windows Imaging Format image:

.WIM

The image can be loaded into memory.

Conceptually:

USB → WIM → RAM → Windows PE

This is why you can troubleshoot a computer even if its internal Windows installation is completely broken.

Microsoft specifically notes that WinPE can boot directly from memory using RAM-disk boot.

Layer 5 — Drivers

WinPE requires drivers to communicate with hardware.

Important examples include:

• USB controllers
• SATA/AHCI controllers
• NVMe controllers
• RAID controllers
• network adapters
• Wi-Fi adapters
• Intel RST
• Intel VMD
• storage controllers

Modern Strelec releases include additional storage-driver packages, and the project's 2026 version history specifically mentions added x64 storage-driver packages.

Layer 6 — Portable Technician Applications

The final layer consists of the recovery and maintenance applications.

This is where Strelec becomes substantially more useful than a basic Microsoft WinPE image.

Strelec and 32-Bit vs 64-Bit Computers

This is especially important when supporting old and new hardware.

Older Strelec distributions have included:

WinPE11 x64

WinPE10 x64

WinPE10 x86

WinPE8 x86

WinPE8 x86 Native

The official 2026 WinPE 11-10-8 release still identifies x86, x64 and Native x86 environments.

This broad architecture coverage is useful for technicians who support machines from different generations.

Legacy BIOS vs UEFI

Understanding this distinction prevents many boot problems.

Legacy BIOS

Common on older computers.

Typical characteristics:

• MBR disks
• traditional BIOS boot
• 32-bit or 64-bit processors
• Windows XP/7-era hardware
• CSM compatibility on some newer PCs

For these computers, a Strelec USB prepared with Legacy/BIOS support can be very useful.

UEFI

Common on modern PCs.

Typical characteristics:

• GPT disks
• EFI System Partition
• 64-bit firmware
• Windows Boot Manager
• Secure Boot
• NVMe SSDs

Modern x64 WinPE is normally the preferred environment.

Microsoft states that:

32-bit WinPE can boot 32-bit UEFI and BIOS PCs and 64-bit BIOS PCs.

64-bit WinPE can boot 64-bit UEFI and BIOS PCs.

That architecture distinction is important when troubleshooting very old or unusual hardware.

Which Strelec Environment Should You Use?

A practical technician rule is:

Computer	Recommended Environment
Modern Windows 11 PC	WinPE 11/10 x64
Windows 10 PC	WinPE 10/11 x64
Windows 8/8.1 PC	WinPE 10 x64 or compatible PE
Windows 7 64-bit PC	WinPE 10 x64 often works
Older 32-bit PC	WinPE x86
Very old/low-memory PC	WinPE 8 Native x86 may be useful
Modern UEFI/GPT PC	x64 UEFI
Old BIOS/MBR PC	Legacy-compatible PE
NVMe system	Modern x64 PE strongly preferred
Intel VMD/RST system	Modern PE with appropriate storage drivers

The operating system installed on the disk does not necessarily have to match the PE version.

For example, a Windows 10/11 PE can often be used to recover files from a Windows 7 installation.

Important Concept: Installed OS vs Boot Environment

Suppose a computer contains:

Windows 7 x64

You may still boot:

Strelec WinPE 10 x64

because the PE environment is running independently.

Similarly:

Windows 11 installed → Strelec WinPE 10/11 → repair disk

The purpose is not to boot the installed Windows version.

The purpose is to boot a compatible recovery operating system capable of accessing the hardware and disk.

How to Create a Strelec Bootable USB

Obtain the image from the project's official source and verify the published checksum whenever possible.

The official releases publish checksums such as CRC32, MD5 and SHA-1 for the ISO.

A USB drive of at least 16 GB is a practical minimum today, although 32 GB or larger is more convenient for a technician's multiboot drive.

Back up the USB first because preparation may erase it.

Method 1 — Dedicated Strelec USB

This approach is appropriate if the USB is primarily intended for Strelec.

General process:

1. Download the official archive/ISO.
2. Verify its checksum.
3. Extract it if required.
4. Follow the USB creation method supplied with the release.
5. Boot the target computer from USB.
6. Select the appropriate PE environment.

Older official Strelec documentation notes that recommended USB-recording methods were included with the distribution.

Method 2 — Strelec with Ventoy

A particularly useful technician setup is:

Ventoy + Strelec + Windows ISOs + Linux utilities

Ventoy is an open-source multiboot system that allows ISO, WIM, IMG, VHD(x) and EFI files to be copied to a USB and selected from a boot menu. It supports Legacy BIOS and several UEFI architectures.

Ventoy's tested WinPE list includes Strelec images, including a WinPE 11-10-8 Sergei Strelec build.

However, compatibility can depend on the particular Strelec and Ventoy versions. Historical Ventoy testing showed that certain older Strelec releases behaved differently between Legacy and UEFI modes.

Therefore, test your exact combination before depending on it for field service.

Example Technician Multiboot USB

A 64 GB or 128 GB Ventoy USB might contain:

Recovery

Strelec WinPE ISO

Windows

Windows 11 ISO
Windows 10 ISO
Windows Server ISO

Linux

Ubuntu Live ISO

Diagnostics

MemTest86 or other bootable diagnostic images

Ventoy then displays a boot menu from which the technician selects the required image.

This is considerably easier to maintain than carrying many individual USB drives.

Booting Strelec on an Older BIOS Computer

Typical procedure:

1. Insert the Strelec USB.
2. Power on the computer.
3. Open the boot menu.

Common keys include:

F12, F11, F9, Esc or F8

depending on the manufacturer.

4. Select the USB device.
5. Choose Legacy/BIOS boot if required.
6. Select an appropriate x86 or x64 PE.

For an old 32-bit system, use an x86-compatible PE if available.

Booting Strelec on a Modern UEFI Computer

Typical procedure:

1. Insert USB.
2. Enter the firmware boot menu.
3. Look for:

UEFI: USB Device

rather than simply:

USB Device

4. Select the UEFI entry.
5. Boot a modern x64 PE.

Microsoft recommends selecting the correct firmware mode because WinPE must be booted in the appropriate UEFI or Legacy mode when Windows is being installed.

Secure Boot and Strelec

Secure Boot deserves special attention.

Because Strelec combines third-party boot components, drivers and applications, Secure Boot compatibility should not be assumed.

The Strelec documentation itself notes that Secure Boot operation is not guaranteed on all computers and recommends disabling it when necessary.

Therefore, if the USB is detected but refuses to boot:

1. Enter UEFI setup.
2. Check Secure Boot.
3. Temporarily disable Secure Boot if required.
4. Boot Strelec.
5. Perform the maintenance operation.
6. Re-enable Secure Boot afterward if the system normally uses it.

Do not unnecessarily change TPM settings or clear the TPM.

On BitLocker-protected systems, firmware changes can trigger recovery-key requirements, so ensure the BitLocker recovery key is available before changing firmware settings.

Microsoft EFI Loader vs GRUB2

Strelec documentation describes two possible UEFI bootloader configurations.

Microsoft EFI loader

Provides conventional EFI booting.

GRUB2

Can provide additional boot functionality and integration with other bootable utilities.

The project's documentation describes batch files for switching between Microsoft EFI and GRUB2 configurations.

This flexibility is particularly useful when building advanced technician USB drives.

What If Strelec Cannot See the SSD?

This is increasingly common on modern laptops.

The likely problem may not be the SSD itself.

The storage controller may be operating through technologies such as:

• Intel RST
• Intel VMD
• RAID
• vendor-specific NVMe controller

Symptoms:

BIOS sees SSD → Strelec does not see SSD

Possible solution:

Load the correct storage driver into WinPE.

Microsoft also recommends adding required storage drivers when WinPE cannot access hardware.

Do not immediately change RAID/VMD/AHCI settings in BIOS because changing the controller mode can cause the installed Windows system to stop booting.

Example: Windows Will Not Boot

Imagine:

Windows 11 → Automatic Repair → Automatic Repair Failed

Boot Strelec.

Then investigate:

1. Is the NVMe SSD detected?
2. Is the GPT partition table intact?
3. Does the EFI System Partition exist?
4. Is the Windows partition readable?
5. Does the Windows folder exist?
6. Is BitLocker enabled?
7. Is the BCD damaged?
8. Is the SSD reporting hardware problems?

You can then decide whether to:

• repair boot files
• restore an image
• recover files
• clone the disk
• reinstall Windows

This is much safer than immediately formatting the machine.

Example: NTFS Drive Becomes RAW

Suppose:

D: NTFS → suddenly RAW

Do not immediately:

• format
• initialize
• repartition
• run destructive repair operations

Instead:

Boot Strelec → Check disk health → Image/clone failing disk → Scan image/disk with appropriate recovery software → Recover data to another disk

This workflow is particularly useful because Strelec contains both diagnostic and data-recovery categories.

Example: HDD Is Physically Failing

If SMART indicates serious hardware problems, avoid repeatedly running deep scans directly against the original disk.

A safer professional workflow is:

Failing HDD → Clone/Image → Healthy Disk/Image File → Recovery Software

The objective is to minimize stress on the failing drive.

Strelec provides several imaging and recovery tools that can assist with this workflow, although severely failing drives should be handled by a professional data-recovery laboratory.

Example: Moving Windows to a New SSD

A technician can use Strelec for:

Old HDD → New SSD

or:

Old SSD → Larger NVMe SSD

Typical process:

1. Boot Strelec.
2. Confirm both drives.
3. Check source-drive health.
4. Launch imaging/cloning software.
5. Clone source to destination.
6. Shut down.
7. Remove old drive if appropriate.
8. Boot from new SSD.
9. Repair EFI/BCD if necessary.
10. Verify partitions.

Example: Recover Files from a PC That Will Not Boot

Suppose Windows is completely corrupted but the disk is healthy.

Boot Strelec.

You can then copy:

C:\Users\User\Desktop

C:\Users\User\Documents

C:\Users\User\Pictures

to:

• external HDD
• external SSD
• another internal drive
• network storage

This can be performed without repairing Windows first.

That is often the safest approach:

Recover important data first → repair operating system second.

Using Strelec for Windows Installation

A useful advanced setup is to keep Windows ISO files on the same technician USB.

You can then boot Strelec and use Windows installation/deployment utilities to prepare the destination disk and launch installation.

This can be useful when conventional Windows Setup has difficulty with:

• partition structures
• imaging workflows
• custom deployment
• multiple Windows versions

Microsoft itself defines Windows deployment and installation as core WinPE scenarios.

BIOS/MBR vs UEFI/GPT — Important Rule

For conventional Windows deployments, remember:

Legacy BIOS → normally MBR

UEFI → normally GPT

For modern Windows 11 systems:

UEFI + GPT is the normal configuration.

Do not randomly convert MBR/GPT simply because a machine will not boot.

First determine:

• firmware mode
• partition scheme
• EFI partition status
• Windows architecture
• bootloader condition

Why Technicians Prefer Strelec

A technician may arrive at a customer site without knowing whether the computer has:

• Windows 7
• Windows 10
• Windows 11
• BIOS
• UEFI
• HDD
• SATA SSD
• NVMe
• RAID
• corrupted Windows
• deleted partition
• RAW drive
• failing disk

A comprehensive WinPE toolkit provides one starting point for all these situations.

That is the primary reason Strelec has become popular among repair technicians.

Strelec vs Normal Windows Installation USB

These should not be confused.

Windows Installation USB

Primarily designed for:

• installing Windows
• upgrading Windows
• basic recovery

Strelec WinPE

Primarily designed for:

• troubleshooting
• diagnostics
• data recovery
• disk imaging
• cloning
• partition management
• offline Windows repair
• advanced deployment

A Windows installation USB is an installer.

Strelec is closer to a portable technician workshop.

Strelec vs Windows Recovery Environment

Windows Recovery Environment (WinRE) normally contains functions such as:

• Startup Repair
• System Restore
• Command Prompt
• uninstall updates
• reset PC

Strelec provides a substantially broader collection of third-party maintenance and recovery utilities.

Therefore:

WinRE = basic Microsoft recovery environment

Strelec = comprehensive third-party technician environment built around WinPE

Strelec vs Hiren's BootCD PE

Both serve similar general purposes.

Hiren's BootCD PE is another popular Windows PE-based rescue environment.

Strelec is often attractive to advanced technicians because of its very broad collection of disk, imaging, recovery, diagnostic and administrative utilities.

The best choice depends on:

• licensing requirements
• required applications
• hardware support
• technician preference
• boot compatibility

There is no requirement to use only one. A Ventoy technician drive can contain multiple rescue environments.

Strelec vs MediCat USB

MediCat is generally designed as a broader multiboot rescue collection.

Strelec is primarily centered around a highly customized Windows PE technician environment.

A technician may therefore build:

Ventoy

→ Strelec WinPE
→ MediCat-compatible utilities where appropriate
→ Windows 11
→ Windows 10
→ Ubuntu
→ MemTest
→ other rescue ISOs

Important Licensing Consideration

This point is frequently overlooked.

Windows PE itself is a Microsoft deployment/recovery technology, but Strelec distributions may include numerous third-party applications.

Some applications may be:

• freeware
• shareware
• trialware
• proprietary
• commercial software

Therefore, the fact that an application exists inside a rescue environment does not automatically grant commercial-use licensing rights.

Businesses, IT companies and technicians should verify the license terms of individual applications before using them commercially.

This is particularly important for corporate IT departments and paid computer-repair businesses.

Security Considerations

A rescue environment has enormous privileges.

It may be capable of:

• reading disks
• modifying partitions
• changing boot configuration
• copying files
• modifying offline Windows installations

Therefore, treat the USB as a privileged administrative tool.

Recommended practices:

1. Obtain Strelec only from a trusted/original source.
2. Verify published hashes/checksums.
3. Avoid modified third-party repacks.
4. Keep the USB physically secure.
5. Scan downloaded archives where appropriate.
6. Maintain backups before partition operations.
7. Never experiment on the only copy of important data.

The official project publishes checksums with releases specifically enabling users to verify downloaded ISO files.

Recommended Technician USB Strategy

For professional IT support, a 64 GB or 128 GB USB 3.x drive is much more practical than a very small flash drive.

A useful structure could be:

BOOT / RECOVERY

Strelec WinPE

WINDOWS

Windows 11
Windows 10
Windows Server

LINUX

Ubuntu Live

DIAGNOSTICS

Memory diagnostics
Manufacturer diagnostics

DRIVERS

Intel RST/VMD
LAN
Wi-Fi
storage drivers

TOOLS

Firmware updates
vendor utilities

This creates a single field-service USB capable of handling both old and modern computers.

Recommended Boot Decision Tree

When arriving at an unknown computer:

Step 1

Determine:

Legacy BIOS or UEFI?

Step 2

Determine:

32-bit or 64-bit hardware?

Step 3

Determine storage type:

IDE / SATA / NVMe / RAID / VMD

Step 4

Choose:

Legacy x86 → very old system

Legacy x64 → older 64-bit system

UEFI x64 → modern system

Step 5

Boot Strelec.

Step 6

Before changing anything:

Check disk health.

Step 7

If disk health is questionable:

Clone/image first.

Step 8

Then perform:

Recovery / Repair / Installation

This order reduces the chance of turning a recoverable problem into permanent data loss.

Disk / Backup / Recovery / Diagnostic / Deployment Utilities

Its greatest value appears when normal Windows cannot be trusted or cannot start.

A technician can boot Strelec and investigate the computer from outside the installed operating system, making it useful for:

Windows boot failure → Strelec → diagnose → repair

Damaged Windows → Strelec → copy data → reinstall

Old HDD → Strelec → clone → new SSD

RAW partition → Strelec → diagnose/image → recover

Deleted partition → Strelec → scan → recover

Windows installation → Strelec → prepare/deploy

Unknown PC → Strelec → inspect hardware and disks

For technicians supporting both old and new computers, maintaining a tested Ventoy + Strelec + Windows installation ISOs + diagnostic tools USB can provide an extremely versatile service toolkit.

The key is to understand that Strelec is not simply a "Windows repair program." It is a complete bootable Windows PE-based maintenance platform that combines Microsoft's lightweight recovery/deployment technology with a large collection of technician-oriented utilities.

For modern systems, use a current x64 UEFI-capable PE wherever possible. For older machines, x86 and Legacy BIOS-compatible environments can remain valuable. And whenever important data is involved, follow the most important recovery principle:

Diagnose first → protect/image the data → repair second.
