Sometimes, Windows users may deactivate the correct partition thereby resulting in the Windows 10 Grub Rescue problem. This is because the BIOS initiates the boot loader from the active partition.

  • Now, Type ‘diskpart’ without quotes and hit the ‘Enter’ key.
  • Type the following commands one after the other:
  • Then type the following commands one by one:
    • list disk: ( this list all hard drives in your computer)
    • select disk n: (n means the disk where the OS is installed. Here you can select disk 0 or any other disk where Windows 10 is installed.)
    • list volume: (this list all volumes on disk 0 is listed.)
    • select volume n: (the n implies the number of the system partitions.)
    • active: (this indicates the active system partition.)
  • From the list of the displayed system partition, determine the right partition which should be active.
  • Type the following command and hit ‘Enter’ after each command:
    • select partition d
    • active
    • quit
  • Restart your PC afterward.

This should resolve the Windows 10 grub rescue error startup problem.
