What is Windows Startup Repair?
Windows Startup Repair (often called
Automatic Repair or Boot Repair) is part of the Windows Recovery Environment
(WinRE). It is “a Windows recovery tool that can fix certain system problems
that might prevent Windows from starting”. When you run Startup Repair, Windows
scans your system for issues such as:
Missing or damaged system files (essential
for Windows to boot).
Corrupted Boot Configuration Data (BCD) –
the data that tells Windows where and how to load.
Damaged Master Boot Record (MBR) or boot
sector.
Incompatible or faulty drivers that hinder
startup.
Registry errors or other boot-related
problems.
If it detects any of these issues, Startup
Repair will attempt to automatically fix them. For example, it might rebuild
the BCD, replace a bad MBR, or restore system files. After the repair, it
restarts your PC to see if Windows can now boot. If successful, your computer
should start normally; if not, the tool gives a report of what it found. In
short, Startup Repair is your first step in addressing boot failures before attempting
more drastic measures, such as reinstalling Windows.
When to Use Startup Repair
You should use Startup Repair whenever
Windows fails to boot or shows startup errors. Common scenarios include:
Blue or black screen on boot. After
powering on, Windows crashes or displays an error (e.g., “Your PC ran into a
problem”).
Startup Repair loop. Windows says
“Diagnosing your PC” or “Preparing Automatic Repair” and keeps rebooting.
Error messages about missing boot files
(like BOOTMGR is missing or Operating System not found).
Frequent crashes before Windows loads the desktop.
If Windows 10/11 won’t load the desktop and
instead repeatedly enters the recovery environment, run Startup Repair. It’s
worth trying before more complex steps. Microsoft’s documentation notes that
when your PC “detects a startup failure”, it will automatically launch the
Automatic Repair (Startup Repair) tool to diagnose and fix issues. But you can
also invoke it manually (we cover that next). In summary, Startup Repair is for
resolving boot problems without affecting your files.
Accessing Windows Startup Repair
To run Startup Repair, you first need to
get into the Windows Recovery Environment (WinRE) or Advanced Startup Options.
Here are the main ways to access it on Windows 10 and 11:
From Within Windows (10/11)
If Windows is still bootable, you can
restart into the recovery environment via Settings:
Windows 11: Go to Start → Settings → System
→ Recovery. Under Advanced startup, click Restart now.
Windows 10: Go to Start → Settings → Update
& Security → Recovery. Under Advanced startup, click Restart now.
Alternatively, you can use the login screen
or command prompt:
Shift+Restart: From the Windows login
screen or Start menu, click Power, then hold Shift while clicking Restart.
Windows will reboot into the recovery menu.
Command Prompt: Open Command Prompt as
administrator and run shutdown /r /o /f /t 00. The PC will restart into WinRE.
These methods take you to the Choose an
option screen (WinRE), where you can select Troubleshoot → Advanced options →
Startup Repair. (We detail this below.)
When Windows Won't Boot (WinRE or
Installation Media)
If Windows can’t start at all, use one of
these methods:
Force WinRE by interrupting boot: Turn on
the PC and as soon as the Windows logo appears, hold the power button to force
shutdown. Repeat this twice. On the third boot, Windows should automatically
enter WinRE (Advanced Startup). Dell’s documentation specifically notes that
after two failed boots, “the third boot will guide the device to the Windows
Repair Environment”.
Use Windows installation or recovery media:
Boot your computer from a Windows 10/11 installation USB/DVD or a recovery
drive. When the Windows Setup screen appears, choose Repair your computer →
Troubleshoot → Advanced options → Startup Repair. This is often the most
reliable method if the system disk isn’t booting.
Boot key on startup: Some PCs (especially
branded ones) have a recovery key (e.g., F9 on ASUS, F11 on HP) to load WinRE.
Check your PC’s documentation for a key to access recovery. (For example, ASUS
says pressing F9 or F12 during boot can enter the WinRE).
Once in WinRE, select Troubleshoot →
Advanced options → Startup Repair. If your drive is encrypted (BitLocker), have
your recovery key handy. After choosing Startup Repair, Windows will restart
and attempt repairs automatically.
Running Startup Repair: Step-by-Step
Here’s a clear, step-by-step guide to
running Startup Repair on Windows 10 or 11:
Enter WinRE (Advanced Startup): Use one of
the methods above (Shift+Restart, Settings, force reboot, or installation
media) until you see the Choose an option screen.
Select Troubleshoot: On the Choose an
option screen, click or tap Troubleshoot.
Choose Advanced Options: In the
Troubleshoot menu, pick Advanced options. This reveals recovery tools.
Select your account: If prompted, choose
your Windows user account and enter its password or PIN.
Wait for diagnostics: Windows will reboot
and launch Startup Repair. You’ll see messages like “Diagnosing your PC” and
then “Working on repairs”. Let it run; it may take several minutes.
Review results: After scanning, Startup
Repair will either fix found issues and reboot, or report that it “couldn’t
repair your PC” and give details. If problems are fixed, Windows should start.
If not, take note of any error messages or code.
Tip: Windows logs what Startup Repair does
to a file at %windir%\System32\LogFiles\Srt\SrtTrail.txt. You can inspect this
via a Command Prompt in WinRE to see details on what failed, though this is
advanced.
Microsoft notes that Startup Repair
“automatically fixes many common problems” and diagnoses issues by checking
system logs. It’s the automated first step in troubleshooting boot errors.
Troubleshooting Common Startup Issues
Even with Startup Repair, you may encounter
stubborn problems. Here are common issues and how to address them:
Automatic Repair / Startup Repair Loop
A known issue is the “automatic repair
loop”, where your PC keeps booting to the recovery environment over and over.
It might show “Diagnosing your PC” then “Automatic Repair”, but never reach the
desktop. To break this loop:
Remove External Devices: First, disconnect
all peripherals (USB drives, printers, external hard disks, etc.). Faulty or
incompatible devices can hang the boot process. After removing them, restart.
Force Shutdown Twice: Force shut down again
(hold power) once or twice more. Windows should offer to launch the advanced
options on the third boot.
Use WinRE Commands: If you can get to
WinRE, try booting into Safe Mode (below) or use Command Prompt tools to repair
(bootrec, bcdedit, etc., see Advanced section).
Update Firmware/Drivers: If you reach the
desktop after forcing a reboot, immediately update Windows, drivers, and
BIOS/UEFI. Outdated firmware often causes boot loops.
In many cases, simply forcing Windows into
the recovery environment by interrupting the boot cycle and then running
Startup Repair once more will fix the loop. Dell’s guide confirms that repeated
boot attempts cause Windows to drop into WinRE automatically.
“Startup Repair couldn’t repair your PC.”
Sometimes, Startup Repair runs but reports
it “couldn’t repair your PC” or “Startup Repair failed to fix your PC”. This
means the automated tool didn’t find or fix the root cause. Possible steps:
Try Again or System Restore: Sometimes,
re-running Startup Repair a second time helps. Otherwise, try System Restore
(see below) to undo recent changes, as ASUS suggests.
Check the log: View SrtTrail.txt (using
Command Prompt in WinRE) to identify specific errors (e.g., bad drivers,
missing files).
Run Command-Line Repairs: Boot into Command
Prompt from Advanced options and manually repair the boot: use bootrec /fixmbr,
bootrec /fixboot, bootrec /rebuildbcd to repair the boot records. Also, run sfc
/scannow (with DISM if needed) to repair corrupt files.
Hardware Checks: Ensure your hard drive is
healthy (run chkdsk /f /r C: from WinRE). A failing drive can block startup.
Also, reseat cables or try a different SATA port on the desktop.
Last Resort – Reset: If nothing works,
consider Reset this PC (Refresh or Remove Everything) as a last resort.
Stuck on “Diagnosing your PC” or “Preparing
Automatic Repair”
If the screen hangs on “Diagnosing your PC”
or “Preparing Automatic Repair” for a long time, try these:
Remove Peripherals: Again, unplug all
external devices (including extra monitors). A stuck Preparing Automatic Repair
often means something is interfering, and ASUS specifically advises
disconnecting everything.
Force Shutdown and CMOS Reset: Power off
completely. For laptops, remove the battery if possible. For desktops, try
clearing CMOS as ASUS suggests. This resets hardware to defaults.
Enter WinRE via Boot Menu: Try pressing the
recovery key (F9/F12 for ASUS, F11 for HP, F8 on some systems) during boot to
force entry to Advanced Options.
Repair from Install Media: If built-in
repair is frozen, boot from Windows USB and use Startup Repair or Command
Prompt from there.
These steps often unstick the freeze. The
key is to eliminate any external cause (by unplugging devices) and then trigger
WinRE through alternate means.
System Not Booting at All
If your PC is completely unresponsive or
won’t get past BIOS/UEFI:
Check Hardware: Ensure the drive is
recognized in BIOS. Listen for unusual drive noises. Try booting from a USB
drive; if that works, the OS installation may be damaged.
Use WinRE Tools: If you can’t run Startup
Repair directly, at least enter Command Prompt from WinRE or install media.
Then run the bootrec and bcdboot commands to rebuild the bootloader and
partition data. For example:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
Try Safe Mode: In Advanced Startup, choose
Startup Settings and then boot into Safe Mode (see below). If Safe Mode loads,
the issue might be a bad driver or software. Uninstall recent apps or drivers.
Last Resort – Reinstall: If all repair
attempts fail, you may need to reinstall Windows. Use Reset this PC (keep files
or wipe clean) or clean install from media.
Advanced Repair Options
If basic Startup Repair doesn’t fix the
issue, use these advanced tools in WinRE:
Using Command Prompt (Bootrec, SFC, CHKDSK)
In the Advanced options screen, select
Command Prompt.
Repair Boot Records: Use bootrec commands
to fix the master boot record (MBR) and boot data:
bootrec /fixmbr – writes a new
Windows-compatible MBR.
bootrec /fixboot – writes a new boot
sector.
bootrec /rebuildbcd – scans disks and
rebuilds the Boot Configuration Data store.
Check Disk for Errors: Run chkdsk C: /f /r
to find and fix disk errors or bad sectors. (Replace C: with your system drive
letter if different.)
System File Checker: If Windows can’t boot
due to corrupted files, run SFC:
sfc /scannow
Or better: first DISM.exe /Online
/Cleanup-image /Restorehealth, then sfc /scannow. This scans and repairs
Windows system files.
Rebuild BCD by hand (if needed): If bootrec
/rebuildbcd fails, use bcdboot C:\Windows (assuming C: is your Windows drive)
to recreate boot files.
Exit and reboot: Type exit and press Enter.
Then restart the PC to see if repairs allowed Windows to start.
These CLI tools give you maximum control.
Microsoft’s guide on boot issues recommends bootrec for MBR/boot sector and
bcdedit for advanced cases. They can often fix problems that the automated tool
missed.
System Restore (Undo Recent Changes)
System Restore rolls your PC back to an
earlier snapshot (restore point) when things were working. It’s especially
useful if your issue started after a recent software change (like a bad driver
or update). System Restore does not affect personal files, only system settings
and programs.
Access System Restore: From WinRE Advanced
options, choose System Restore (not to be confused with a full reset). You must
have had a restore point created earlier.
Select a Restore Point: Choose a point
dated before the problem began.
Apply and reboot: Windows will restore to
that state and reboot.
ASUS and Microsoft both note this:
“Performing a system restore will not change your files but might remove
recently installed applications and drivers”. It’s a safe way to undo recent
harmful changes. If System Restore isn’t available or doesn’t fix it, move on.
Safe Mode (Troubleshoot in Minimal State)
Safe Mode starts Windows with only
essential drivers/services. If Windows won’t boot normally but works in Safe
Mode, you can uninstall drivers or programs causing problems.
Enter Safe Mode: In Advanced options, click
Startup Settings, then Restart. After reboot, press F4 (or the number key) for
Enable Safe Mode (no networking) or F5 for Safe Mode with Networking.
Alternatively, while in WinRE, choose Startup Settings and then the relevant
option.
Check System: If Safe Mode loads, go to
Device Manager or Programs and Features and remove anything recently installed
(e.g., a new graphics driver or app).
Exit Safe Mode: Simply restart normally. If
Windows now boots, you have found the culprit.
Dell explains that Safe Mode is accessed
via the Startup Settings menu in WinRE, and that if a problem “doesn’t happen
in Safe Mode, default drivers or services aren’t causing it”. Safe Mode is a
core troubleshooting step.
System Image Recovery
If you have a system image backup, you can
restore your entire Windows installation to a previous point. In WinRE Advanced
options, choose System Image Recovery and select your backup. This overwrites
everything on the system drive with the image (useful if all else fails and you
have a good backup). This option is only available if you previously created an
image with Windows Backup or third-party tools.
Other Windows Recovery Options
If Startup Repair and the above options
don’t work, consider these broader recovery tools:
Reset This PC (Refresh/Reinstall Windows)
Windows 10/11 includes Reset this PC, which
reinstalls Windows while optionally keeping personal files. ASUS describes two
modes:
Keep my files: Reinstalls Windows and
removes apps/settings, but retains your files.
Remove everything: Erases all files, apps,
and settings, then reinstalls Windows.
To use Reset, go to WinRE Troubleshoot →
Reset this PC, then choose an option and follow prompts. This is effectively a
fresh OS install with minimal hassle. It’s like a factory reset. Use it if
other repairs fail, but you can still access WinRE. Dell and ASUS both note that
resetting is a final step if startup repair and restore fail.
Recovery Drive or Installation Media
Recovery Drive: If you previously created a
USB recovery drive, boot from it and select Recover from a drive (Windows 10)
to refresh or reset Windows.
Installation Media: Boot from Windows 10/11
USB/DVD. In the setup, select Repair your computer. From there, you can run
Startup Repair, Command Prompt, or fully reinstall Windows.
Using media is also the way to do an
in-place upgrade (see below) if Windows is unstable.
In-Place Upgrade or Clean Install
In-Place Upgrade: Boot from Windows 10/11
install media, choose Install Now → Upgrade. This reinstalls Windows over
itself without losing data, often fixing deep system issues. Computerworld
notes that Step 3 of the repair is an in-place upgrade.
Clean Install: If nothing else works, back
up your data (if possible) and do a clean install of Windows from media. This
erases the system drive and installs a fresh OS.
Both options are covered in guides like
Computerworld. An in-place reinstall keeps apps/data (if done correctly); a
clean install starts from scratch. These are the ultimate fallbacks.
Tips and Best Practices
Keep backups: Always maintain regular
backups or system images. That way, if startup repair fails, you can restore
data or the entire system easily.
Safe remove hardware: Remove USBs, SD
cards, and even external graphics cards when diagnosing boot issues, as
peripherals can hang the process.
Update regularly: Once your PC is fixed,
install all Windows Updates, drivers, and firmware/BIOS updates. Many boot
problems stem from outdated firmware or drivers.
Know your BitLocker key: If your system
drive is BitLocker-encrypted, accessing repair tools requires the recovery key.
Keep it in a safe place (Microsoft account, printout, USB).
Use Safe Mode for fixes: When possible,
boot to Safe Mode to uninstall suspect drivers or software, then reboot
normally.
Disk Health: Use tools like chkdsk to check
disk health. A failing SSD/HDD often causes intermittent boot failures.
Note error codes: If you see a specific
error (like 0xC0000225, BSoD codes, etc.), search it in Microsoft’s docs or
forums. Sometimes, one specific command (e.g., bcdboot) is the key.
Support resources: Check Microsoft’s
official support pages for the latest guidance (e.g., Startup
Repair, System
Restore) or forums like Answers.microsoft.com for community tips.
Preventive maintenance: Enable System
Restore on your drives (via System Protection settings) so you always have
restore points available.
Conclusion
Dealing with Windows startup problems can
be stressful, but the built-in Windows Startup Repair and recovery tools
provide multiple ways to diagnose and fix boot issues on Windows 10 and 11.
Start by running Startup Repair via the recovery environment (WinRE). If
Windows won’t boot normally, use installation media or forced reboots to access
WinRE.
If automatic repair doesn’t resolve the
issue, troubleshooting steps include removing external devices, checking for
corrupted boot files (bootrec, bcdedit), and using tools like System Restore or
Safe Mode. Dell and ASUS support guides highlight important strategies:
disconnect peripherals, update firmware/drivers after repair, and use Safe
Mode/System Restore when needed. As a last resort, resetting or reinstalling
Windows will get you back to a clean state.
In summary, “Windows Startup Repair” is a
powerful first step, but knowing the complete recovery toolkit (Command Prompt
repairs, Restore, Safe Mode, Reset) gives you the best chance to fix startup
problems and recover your Windows 10/11 system. With careful, step-by-step
troubleshooting, you can handle most boot failures without losing your data or
having to replace your PC.
