Access Denied? Fixboot Windows 10 Bootrec Error

Are you experiencing the “Access Denied” fixboot Windows 10 bootrec error? Let’s explore how to address this issue.

Utilize Startup Repair to Address Boot Issues

If you encounter boot issues on your Windows 10 system, you can try using the Startup Repair feature to resolve the problem. This tool can help fix errors that prevent your computer from booting properly.

To access Startup Repair:
1. Insert your Windows installation disc or USB flash drive and restart your computer.
2. Press any key to boot from the installation media.
3. Select your language, time, currency, and keyboard preferences, then click “Next.”
4. Click “Repair your computer” at the bottom left of the window.
5. Select “Troubleshoot” > “Advanced options” > “Startup Repair.”

Once you’ve accessed Startup Repair, the tool will attempt to diagnose and fix any issues preventing your computer from booting. It will scan for problems and automatically repair them if possible.

If Startup Repair is unable to resolve the boot issue, you may need to consider other troubleshooting methods such as using the Command Prompt to run bootrec commands or performing a system restore.

Recreate Boot Sector and Rebuild BCD

Windows boot sector and BCD

If you encounter an “Access Denied” error while trying to fix the boot sector or rebuild the BCD in Windows 10, you can follow these steps to resolve the issue.

First, you’ll need to access the Command Prompt with administrative privileges. To do this, press the Windows key, type “cmd” into the search bar, and then right-click on “Command Prompt” and select “Run as administrator.”

Once in the Command Prompt, type the following command to rebuild the boot sector:

bootrec /fixboot

Press Enter to execute the command. This will attempt to fix any issues with the boot sector that may be causing the “Access Denied” error.

Next, you can rebuild the BCD by typing the following command:

bootrec /rebuildbcd

Press Enter to execute the command. This will scan for any Windows installations on your computer and then prompt you to add them to the BCD. Type “Y” and then press Enter to confirm.

If you continue to encounter the “Access Denied” error, you may need to check the permissions on the boot sector and BCD files. To do this, you can use the attrib command to change the permissions:

attrib -s -h -r C:\boot\BCD

Press Enter to execute the command. This will remove the system, hidden, and read-only attributes from the BCD file. You can then try running the bootrec commands again to see if the issue has been resolved.

If you’re still unable to fix the boot sector or rebuild the BCD, you may need to use a Windows installation or recovery disc to access the Command Prompt and perform these steps.

Perform a CHKDSK Command to Check Disk Integrity

  1. Open Command Prompt as an administrator by searching for “cmd” in the Windows search bar, right-clicking on Command Prompt, and selecting “Run as administrator.”
  2. Type chkdsk C: /f /r and press Enter. Replace “C:” with the letter of the drive you want to check, if it’s not the C: drive.
  3. Follow the on-screen instructions to schedule the disk check for the next time you restart your computer.
  4. Restart your computer to allow the CHKDSK command to run and check the disk integrity.

Safeguard Data and Consider System Reinstallation Options

To safeguard data before attempting to fix the bootrec error in Windows 10, consider backing up important files and documents to an external storage device or cloud-based service. This will prevent any potential data loss during the troubleshooting process.

Once data is secure, consider system reinstallation options as a last resort. This may involve using a Windows installation disc or USB flash drive to access the “Repair your computer” option and utilize the Command Prompt for advanced troubleshooting.

It’s important to be cautious when making changes to the system, as incorrect commands or modifications can lead to further issues. Always double-check commands before executing them to ensure they are accurate.

If the bootrec error is preventing Windows from starting properly, accessing the Advanced Boot Options menu by continuously pressing the F8 key during startup may provide additional troubleshooting options.

In some cases, using the System File Checker (sfc) and Deployment Image Servicing and Management (DISM) tools can help repair corrupted system files that may be causing the bootrec error.

Remember to always follow best practices for system maintenance, such as keeping regular backups and performing disk checks to prevent potential errors from occurring in the future.

By taking these precautions and considering system reinstallation options, it is possible to address the bootrec error in Windows 10 and regain access to the operating system.
