Before You Start to Fix Error 0xc0000001 in Windows 11

Below are most of the solutions that will need the use of the Windows Recovery Environment (WinRE). You can press F8 to startup settings and access Advanced Recovery options.

Fix: Error Code 0xc0000001 in Windows 11

Error Code 0xc0000001 in Windows 11 can hamper accessing the Windows desktop. This doesn’t necessarily entail a complete reinstall of Windows, though. You can solve this error by following the 5 methods below.

Fix 1: Run Startup Repair

When your Windows 11 fails to boot up due to any reason, you will see this error code 0xc0000001. Also, you can fix this error code using the Startup Repair option. A Windows utility program that searches for common Windows startup problems such as bad startup files, and/or startup configuration problems.

1. Press on the button to turn on the computer/laptop. And, let the Windows Recovery screen appear.

2. Now, click Troubleshoot > Advanced options.

3. Select Startup Repair. Log into your user account; if asked for your password, do so.

Run Startup Repair from Advanced options
Run Startup Repair

Let Windows identify and troubleshoot start-up issues. When finished, reboot. If Startup Repair doesn’t solve the problem, proceed to the next method.

Fix 2: Run System Restore

If any applications, drivers or system updates were installed or changes were made to your system, then System Restore may be able to help you. It undoes the changes made when the system was restored back to a previous restoration point. This helps bring back system settings and important system files. This generally won’t affect personal files.

1. Go to Windows Recovery Environment (WinRE). Then, navigate to Troubleshoot > Advanced options> System Restore.

2. Click on your Windows user account. If needed, enter your password.

Enter password in Startup Repair

3. Remember to select a restore point prior to when Windows was behaving normally. Tap on Next > Finish and confirm the restore. Once the process has completed, restart the computer.

Fix 3: Use Command Prompt to Repair Boot Files

Error 0xc0000001 in the boot could be a result of damaged Boot Configuration Data (BCD) or other boot files. In WinRE, you can rebuild the boot configuration using Command Prompt.

1. Click on the option in Troubleshoot > Advanced options > Command Prompt.

Command Prompt CMD in WinRE
Command Prompt CMD in WinRE

2. Run the following command.

bootrec /scanos
bootrec scanos
bootrec scanos

3. Then run.

bootrec /rebuildbcd
bootrec rebuildbcd
bootrec rebuildbcd

If a Windows installation is found, follow the on-screen instructions to add it to the boot configuration.

4. You can also use the following command.

bootrec /fixmbr
bootrec fixmbr
bootrec fixmbr

Restart your computer and see if Windows starts up normally. For some UEFI systems “bootrec /fixboot” might show an access-denied error. If that is the case, use “bcdboot” to rebuild the EFI boot files might be more appropriate.

Fix 4: Run SFC to Repair Corrupted System Files

Caused by corrupted or missing Windows files, Error Code 0xc0000001 appears in Windows 11. System File Checker (SFC) can check for and fix corrupt protected system files if it can.

1. Press F8 to start the Windows Recovery Environment, and then press ‘R’ to open Command Prompt.

2. Determine where Windows is installed. For example:-

dir C:\

Search for the “Windows” folder. If it doesn’t appear, then use a different drive letter.

Find Windows in directory
Find Windows in directory

3. Once the proper drive is determined, run.

sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
System File Checker scan
System File Checker scan

Update – If applicable, change the drive in the C: to the appropriate Windows drive. Now, wait until the scan is complete (100%). If so, it’s likely you’ll need to restart the system and see if the startup error has been corrected.

Fix 5: Repair a Damaged SAM File

It is an advanced solution and should be used with caution since the replacement of Registry files may make Windows non bootable in the event that incorrect Registry files are replaced. Whenever possible, make a copy of the existing files before proceeding.

1. Again, open Command Prompt in the Windows Recovery Environment.

Command Prompt CMD in WinRE
Command Prompt CMD in WinRE

2. Determine the drive you are installing Windows onto:-

cd /d C:\Windows\System32\config
config
config

3. Go to the ‘Registry configuration’ folder. Test to see if there is a Registry Backup:-

dir RegBack
dir RegBack
dir RegBack

If backups can be used, do not delete and replace the existing SAM file. RegBack might not include any valid automatically created Registry backups for a modern Windows installation. If you have a known good system backup or restore point, then utilize that recovery option instead.
