2. Run System File Checker (SFC) to Repair Corrupted Files
If corrupted system files are causing the "Startup Repair couldn't repair my computer" error, running the System File Checker (SFC) tool can help fix them. This built-in Windows tool scans your system for corrupted files and attempts to replace them with the correct versions.
Here's how to run the SFC scan:
- Restart your computer and boot into Windows Recovery Environment (WinRE) by pressing F8 during boot or using a Windows installation media.
- Once in WinRE, open the Command Prompt by selecting "Troubleshoot" > "Advanced options" > "Command Prompt."
- In the Command Prompt window, type the following command: sfc /scannow
- Press Enter and wait for the scan to complete. If the tool finds any errors, it will attempt to fix them automatically.
- Restart your computer and check if the issue persists.
If SFC doesn't fix the problem, you may need to try other solutions like repairing the boot configuration data.
3. Repair the Boot Configuration Data (BCD)
The Boot Configuration Data (BCD) contains boot-related information that tells your system how to start the operating system. If the BCD is corrupted, it can prevent your computer from booting properly. Repairing the BCD might resolve the startup repair issue.
To repair the BCD, follow these steps:
- Boot into the Command Prompt in WinRE as described above.
- Type the following command and press Enter: bootrec /fixmbr
- Next, type: bootrec /fixboot
- Then, type: bootrec /rebuildbcd
- Restart your computer to check if the error is resolved.
If this doesn’t solve the issue, try using a Windows installation disk to perform a system restore or reset your PC.
4. Use System Restore to Roll Back to a Previous State
System Restore allows you to restore your computer to a previous working state by using restore points created automatically or manually. If the startup issue started recently, using a System Restore point may help resolve the issue.
Here's how to use System Restore:
- Boot into WinRE and select "Troubleshoot" > "Advanced options" > "System Restore."
- Follow the on-screen prompts to choose a restore point prior to the error.
- Let the system restore process complete and check if the error has been resolved after rebooting your PC.
System Restore is an effective method if the issue is related to recent changes made to your system, such as software installations or updates.
5. Check for Hardware Issues: Test Your Hard Drive and RAM
Hardware problems can sometimes cause the "Startup Repair couldn’t repair my computer" error, especially if your hard drive or RAM is failing. Testing these components can help identify any underlying hardware issues that may need attention.
To test your hard drive:
- In WinRE, open Command Prompt and type: chkdsk C: /f to check the system drive for errors.
- If errors are found, the system will attempt to fix them.
For RAM testing, you can use the Windows Memory Diagnostic tool, which can be accessed via WinRE under "Troubleshoot" > "Advanced options" > "Memory Diagnostic."
6. Reset Your PC as a Last Resort
If none of the above methods work, resetting your PC can be an effective last resort. Resetting your PC reinstalls Windows, which can resolve issues that are too complex for simple fixes.
To reset your PC:
- In WinRE, select "Troubleshoot" > "Reset this PC."
- Choose whether you want to keep your files or remove everything.
- Follow the prompts to complete the reset process.
Keep in mind that resetting your PC will remove applications and settings, so it’s recommended to back up important data before proceeding with this option.
