What is bootrec/fixboot?

During our daily computer use, we inevitably encounter some unknown computer problems, such as sector corruption, boot failure, etc. Many users resort to a tool called bootrec.exe to fix Windows startup problems.

Bootrec (bootrec.exe) tool is used to recover a failed, non-working or unresponsive operating system in Windows Recovery Environment (Windows RE). It can repair corrupted Master Boot Records (MBR), boot sectors, and boot configuration data (BCD) storage. This is useful for troubleshooting and possibly repairing errors that prevent the computer from booting.

The fixboot command is normally used to write a new partition boot sector to the system partition, and fix a number of startup errors and problems like blue screen on Windows 11, missing of bootmgr, etc. However, during this repair process, you may encounter that running the bootrec/fixboot command returns the error message “Access is denied”. Why does that error occur? What should we do?

Well, don’t get panic. This article provides you with all possible solutions to the bootrec fixboot access is denied in Windows 11/10/8/7 issue.

How do I fix bootrec/fixboot access denied in Windows?

This error in Windows bootrec/fixboot access is denied occurs due to various reasons. Here, I have summarized the three most likely reasons shared below:

◈ If there is a startup setting that you want to avoid or remove, but the Boot manager processes it by using bootrec/fixboot command in the CMD, then the Access is denied error will be displayed on the screen.
◈ A corrupted or damaged BCD and Windows file is another cause behind the error.
◈ According to many user cases feedback from the Microsoft Community, Windows 10 1707 or Windows 10 1709 versions are not suitable for using the bootrec/fixboot command and the risk of getting Access is denied errors is high. This is the most likely reason.

Well, after having an understanding of why this error alert appears, we will then discuss how to solve the problem. Below you will gain a list of the three most practical ways that may take effect.

Startup Repair can solve some common startup problems in Windows. If you can’t boot your PC normally, it is suggested to try the simple tool first in WinRE before some complex methods.

1. Shut down your computer at the startup screen, and repeat it three times to boot into WinRE.

2. Select Troubleshoot＞Advanced options＞Startup Repair. Immediately it starts to detect and will try to fix the errors it has found.

If there are issues with startup, you’ll be able to see them and choose how Windows handles them. If Startup Repair finds nothing to fix, then you can try the next method.

#2. Repair Bootloader

Your access may be denied because you’re having issues with your EFI system partition. To fix your issue, you should try using the DiskPart utility to reassign a drive letter to your EFI system partition and reformat it.

1. Boot into WinRE, when you see the Automatic Repair screen, click Advanced options＞Troubleshoot＞Command Prompt.

2. Input these two commands one by one into the Command Prompt window and hit Enter on your keyboard to run them in order.

> diskpart > list disk

>select disk 0

3. Type the following line to list all the volumes on this drive:

>list vol

>select vol 1 (1 refers to your EFI volume number and it differs depending on your system configuration)

4. Type the following line and press Enter to reassign a driver letter to this volume: (V can be replaced by any other letter that hasn’t been used by the other volumes.)

>assign letter=V:

5. Type exit and press Enter to leave diskpart.

6. Type V: (the drive letter that you just assigned) and hit Enter. Type the following line and press Enter to reformat this volume:

>format V: /fs:fat32

7. Type the following line and hit Enter:

>bcdboot c:\windows /s V: /f uefi

8. Close the Command Prompt window and then open it again. Then check to see if you’re able to run the “bootrec /fixboot” command.

#3. Run CHKDSK

Check Disk is a tool that can find and fix your system errors. You can run it from the command line using Command Prompt.

1. Once you boot into WinRE, when you see the Automatic Repair screen, click Advanced options＞Troubleshoot＞Command Prompt.

2. Type chkdsk c: /r (If your system partition’s drive letter differs, type the correct one.) into the command prompt and press Enter. It implies you have Windows on your C: drive.

3. CHKDSK will scan for drive errors and let you know if it found any you should repair, Wait for the process to complete, then check to see if you’re able run the “bootrec /fixboot” command.

After trying the bootrec fixboot access denied fix, if each of these methods does not work properly, then you need to use a third-party tool to bring your computer back.
