The Windows boot error 0xc00000e often appears as a blue screen during startup, preventing your system from loading properly. This error typically indicates issues with the Boot Configuration Data (BCD) or critical system files. While frustrating, there are several effective methods to address this problem and get your system running again.
Rebuild the Boot Configuration Data (BCD)
Corrupted BCD is a common cause of the 0xc00000e error. Rebuilding it can often resolve the issue.
Step 1: Boot your computer using a Windows installation media (USB or DVD).
Step 2: On the Windows Setup screen, click “Next”, then “Repair your computer”.
Step 3: Navigate to Troubleshoot > Advanced options > Command Prompt.
Step 4: In the Command Prompt, enter these commands in order, pressing Enter after each:
bootrec /scanos
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
Step 5: Type exit and press Enter to close the Command Prompt, then restart your computer.
This process scans for Windows installations, repairs the Master Boot Record, fixes boot sector issues, and rebuilds the BCD store.
Run the Startup Repair Tool
Windows’ built-in Startup Repair tool can diagnose and fix various boot-related issues.
Step 1: Boot from Windows installation media and select “Repair your computer”.
Step 2: Choose Troubleshoot > Advanced options > Startup Repair.
Step 3: Select your Windows installation and let the tool run its diagnostics and repairs.
This automated process can resolve many common startup problems without requiring manual intervention.
Check and Repair Disk Errors
Disk errors can lead to boot problems. Use the Check Disk utility to scan for and repair these issues.
Step 1: Boot to the Command Prompt using Windows installation media as described earlier.
Step 2: Run the following command, replacing C: with your Windows drive letter if different:
chkdsk C: /f /r
Step 3: Wait for the scan to complete, which may take some time depending on your disk size.
The /f flag fixes errors, while /r locates bad sectors and recovers readable information.
Restore System Files with SFC and DISM
Corrupted system files can cause boot errors. The System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can help restore these files.
Step 1: Boot to the Command Prompt using Windows installation media.
Step 2: Run the following commands in order:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
dism /image:C:\ /cleanup-image /restorehealth
Replace C: with your Windows drive letter if different.
Step 3: Restart your computer after the commands complete.
These tools scan for and replace corrupted system files, potentially resolving the boot error.
Reset BIOS/UEFI Settings
Incorrect BIOS or UEFI settings can sometimes cause boot errors.
Step 1: Restart your computer and enter the BIOS/UEFI setup (usually by pressing F2, Del, or Esc during startup).
Step 2: Look for an option to reset to default settings. This is often labeled “Load Setup Defaults” or “Reset to Factory Settings”.
Step 3: Save changes and exit the BIOS/UEFI setup.
Step 4: Allow your system to restart and check if the error persists.
Resetting BIOS/UEFI can resolve issues caused by misconfigured settings, but be cautious as this will reset all BIOS/UEFI customizations.
If these methods don’t resolve the 0xc00000e error, you may need to consider more drastic measures like performing a clean Windows installation or seeking professional technical support. Always ensure you have backups of important data before attempting major system repairs or reinstallations.
