Windows 10更新后驱动器损坏无法启动，两台设备自动修复异常求助

Hey there, sorry to hear your Dell desktop got stuck in the Automatic Repair loop after that unexpected restart—let’s walk through targeted fixes to get it back up and running. The error you’re seeing usually points to boot configuration issues, corrupted system files, or problematic updates, so let’s start with the most actionable steps:

The log file mentioned (C:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt) will tell you exactly what’s failing during repair. To access it:

• Create a Windows 10 installation USB/disc (you can use your working Lenovo laptop to make this via the Media Creation Tool)
• Boot your Dell from the installation media, select "Repair your computer" > "Troubleshoot" > "Advanced options" > "Command Prompt"
• Run this command to open the log:
  notepad C:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt
  Look for keywords like "BCD error", "corrupted system file", or "hard drive failure"—this will narrow down your next step.

BCD issues are the #1 cause of Automatic Repair loops. From the same Command Prompt window:

• Run these commands one by one, pressing Enter after each:
  • bootrec /scanos (scans for Windows installations)
  • bootrec /fixmbr (repairs the master boot record)
  • bootrec /fixboot (repairs the boot sector)
  • bootrec /rebuildbcd (rebuilds the boot configuration database)
    When prompted to add found Windows installations, type Y and press Enter. Restart your PC afterward to test.

If the log mentions corrupted system files, run these offline scans:

• First, confirm your system drive letter (it might not be C:—use diskpart > list volume to find the volume labeled "System", note its letter e.g., D:)
• Run the System File Checker:
  sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows
• If SFC can’t fix all issues, run DISM to restore system image health:
  DISM /Image:D:\ /Cleanup-Image /RestoreHealth /Source:WIM:D:\sources\install.wim:1 /LimitAccess
  (Replace D: with your actual system drive letter; if using a USB install media, you may need to assign it a drive letter via diskpart first)

Sometimes a faulty Windows update triggers this loop. Here’s how to remove it:

• From the "Advanced options" menu, select "Uninstall updates"
• Choose either "Uninstall latest quality update" or "Uninstall latest feature update" and follow the prompts
• If that option isn’t available, use Command Prompt:
  1. List installed updates: wmic qfe list brief /format:table
  2. Uninstall the latest one with: wusa /uninstall /kb:XXXXXXX (replace XXXXXXX with the KB number from the list)

A failing hard drive can also cause boot issues. Run this command in Command Prompt to scan and repair:
chkdsk D: /r /f
(Again, replace D: with your system drive letter) This will take time—let it finish completely before restarting.

If all else fails, you’ll need to refresh or reset Windows. First, back up your data:

• In Command Prompt, copy files to a USB drive (assign the USB a letter via diskpart first):
  xcopy D:\Users\YourUsername\Documents E:\Backup\Documents /E /H /C /I
  Then go to "Troubleshoot" > "Reset this PC":
• Choose "Keep my files" first—this preserves your personal data but reinstalls Windows
• If that fails, select "Remove everything" (ensure you’ve backed up all critical data first)
