You power on your Acer laptop and instead of the familiar login screen you get a blue “Automatic Repair” screen telling you it couldn’t repair your PC, and the log file points to SrtTrail.txt. It is one of the most frustrating Windows errors because the built-in repair tool spins its wheels, fails, and drops you right back where you started.
The good news is that this error is very fixable. In almost every case I have seen, the cause is a corrupted bootloader, damaged system files, or disk errors — all things you can repair yourself with a few commands. Let’s walk through it.
Why this happens
- Corrupted boot configuration data (BCD): The small database Windows uses to find its own startup files gets damaged by a bad shutdown, a failed update, or a power cut, so the bootloader cannot finish loading.
- Damaged system files: Core Windows files required at startup (like winload.exe or the registry hives) become corrupted, and Automatic Repair cannot replace them on its own.
- Disk errors or a failing drive: Bad sectors on the system partition interrupt the boot process; this is the most common hardware cause of a recurring SrtTrail loop.
- A broken driver installed just before the crash: A faulty storage controller, chipset, or graphics driver that loads at boot can blue-screen Windows before the desktop ever appears.
- A Windows update that did not finish cleanly: Feature updates rewrite boot files, and if the update is interrupted, the system is left in a half-updated state that will not start.
- Dual-boot or partition changes: Resizing partitions or installing a second operating system can break the Windows boot entries and trigger the repair loop.
- Fast Startup conflicts on Acer machines: Acer laptops ship with Fast Startup enabled, and a corrupted hibernation file can block a clean boot cycle.
How to fix it
Work through these in order, starting at Fix 1. Most people are booting normally again by Fix 4.
Fix 1: Break the Automatic Repair loop
The loop itself is the first problem — Windows keeps launching Automatic Repair, failing, and rebooting into the same failure. Disable it so you can attempt a normal boot.
- On the blue “Automatic Repair couldn’t repair your PC” screen, click Advanced options.
- Go to Troubleshoot > Advanced options > Command Prompt.
- Type
bcdedit /set {default} recoveryenabled Noand press Enter. You should see “The operation completed successfully.” - Type
exitand press Enter, then choose Continue to restart. - If Windows boots, great — but still run Fixes 4 and 5 afterwards, because the underlying corruption is still there. If it blue-screens again, continue to Fix 2.
Disabling recovery does not remove your files or settings; it just stops Windows from launching the failing repair tool on every boot. For more on general boot-failure recovery, see our guide to fixing blue screen errors on Windows 11 .
Fix 2: Rebuild the boot records
The Master Boot Record and boot configuration data are the most likely culprits. Rebuild them from the recovery Command Prompt.
- Return to Troubleshoot > Advanced options > Command Prompt as in Fix 1.
- Run these commands one at a time, pressing Enter after each:
bootrec /fixmbrbootrec /fixbootbootrec /scanosbootrec /rebuildbcd - If
fixbootreturns “Access is denied,” first rundiskpart, thenlist vol, find the EFI partition (FAT32, around 100 MB), assign it a letter withassign letter=Z:, typeexit, and runbcdboot C:\Windows /s Z: /f UEFI. - Restart and try a normal boot.
Fix 3: Run CHKDSK on the system drive
Disk errors are a leading cause of SrtTrail loops, especially on older Acer laptops with spinning hard drives.
- Open the recovery Command Prompt again.
- First confirm your Windows drive letter — in recovery it is often not C:. Type
diskpart, thenlist vol, note the letter of the large NTFS volume, thenexit. - Run
chkdsk C: /f /r(replace C: with the correct letter if needed). - The scan can take 30 minutes to a few hours on a large drive. Let it finish completely — do not interrupt it.
- Restart and test the boot.
Fix 4: Repair system files with SFC and DISM
If the boot records are fine, corrupted Windows system files are the next suspect.
- From the recovery Command Prompt, run:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows(Adjust the drive letter to match your Windows volume.) - Wait for the scan to reach 100%. It repairs damaged protected files from a cached copy.
- Then run the DISM repair:
DISM /Image:C:\ /Cleanup-Image /RestoreHealth - Restart the laptop normally.
If you later find Windows boots but crashes under load, our walkthrough on Windows stuck on the restarting screen covers the next layer of startup troubleshooting.
Fix 5: Disable Early-Launch Anti-Malware protection
A corrupted ELAM driver can block the boot chain and produce exactly this repair loop.
- On the recovery screen go to Troubleshoot > Advanced options > Startup Settings and click Restart.
- When the options list appears, press 8 (or F8) for “Disable early launch anti-malware protection.”
- If Windows boots, immediately update your antivirus and run a full scan, then restart normally to confirm the fix holds.
- If the system only boots with ELAM disabled, uninstall and reinstall your third-party antivirus — its ELAM driver is damaged.
Fix 6: Use Acer’s built-in recovery or System Restore
Acer laptops include a factory recovery partition you can reach even when Windows will not start.
- Power the laptop off completely, then power on and immediately hold Alt + F10 until the Acer recovery screen appears.
- Choose Troubleshoot, then try System Restore first — pick a restore point dated before the problem began. This keeps all your personal files.
- If no restore point exists, use Startup Repair from Acer’s menu once more, then retry the fixes above if it fails.
Fix 7: Reset Windows while keeping your files
When nothing else works, a reset reinstalls Windows but preserves your documents.
- From Troubleshoot, select Reset this PC.
- Choose Keep my files, then select Cloud download if you have internet (it fetches fresh, uncorrupted Windows files) or Local reinstall if not.
- Follow the prompts. The process takes 30-90 minutes.
- After the reset, install all Windows updates and your Acer drivers from Acer’s official support downloads page. If Windows Update misbehaves after the reset, the official Microsoft Windows support page has the standard troubleshooting steps.
Closing
The SrtTrail.txt loop looks scary, but it is almost always a software problem with a software fix — corrupted boot data, disk errors, or broken system files. Start with the boot record rebuild and CHKDSK, since those two resolve the majority of cases I encounter on Acer laptops. If the loop keeps returning after repairs, take it seriously as a possible drive failure and back up your data immediately, because no command can fix hardware that is on its way out.
