If the "Access is denied" error with bootrec /fixboot is related to your EFI System Partition, try reassigning a drive letter to the partition and formatting it using the DiskPart utility. Follow this guide to fix the bootloader from the Command Prompt.

Step 1: Boot into the Windows Recovery Environment, then select Troubleshoot > Advanced options > Command Prompt.

Step 2. Assign a new drive letter to the drive. Type each of the following commands, pressing Enter after each one.

  • diskpart
  • list disk

Step 3: Format the drive. Type each of the following commands, pressing Enter after each one.

These are examples of Windows Command Prompt commands: 1. z: This command switches to drive Z: in the Command Prompt. 2. format z: /fs:fat32 This command formats drive Z: with the FAT32 file system. Make sure to back up important data before executing this, as it will erase everything on the drive. 3. bcdboot c:\windows /s z: /f uefi This command sets the Boot Configuration Data (BCD) for booting in UEFI mode on drive Z:. It's typically used after a new or recovery operating system installation to set up the boot loader. Here, "c:\windows" refers to the location of your Windows installation.

Step 4: Repair the boot record by typing each of the following commands, pressing Enter after each one:

  • Change to the /d directory
  • Run the command: bootrec /FixBoot
  • Rename the BCD file to BCD.bak
  • Use the bcdboot command: bcdboot C:\Windows /l en-us /s x: /f ALL
  • Run the command bootrec /rebuildbcd to rebuild the BCD

These commands should repair the boot loader. Restart Command Prompt, and then check if you can run the `bootrec /fixboot` command.

Method 3: Rebuild the MBR

If you want to use Bootrec.exe to fix the corrupted MBR but somehow failed, you can turn to Partition Master. It has the ability to rebuild MBR, and it might also help you solve the “Access is denied when running bootrec /fixboot” error. If your computer fails to start, you need to create bootable media from a working computer first, and then run Partition Master on the problematic computer.

Step 1: Create a bootable WinPE disk
