How to Remove Ubuntu from BIOS Menu Permanently


For reasons too long to explain, I reluctantly removed Ubuntu from my computer. After completely removing it and deleting the partition that it was installed onto, I discovered that I still had two Ubuntu entries in the boot order in my BIOS menu. I deleted them by following the instructions in this answer:

As I was doing it, everything appeared to go smoothly. However, upon reboot one of them came back. What's going on here? How do I delete it permanently?

Best Answer

  1. Boot on a Ubuntu 64-bit disk, choose Try Ubuntu.

  2. Open a terminal and type the following commands:

    sudo mount /dev/sda2 /mnt
    sudo rm -r /mnt/EFI/ubuntu
    sudo efibootmgr

    This should display your boot entries, each with a number. E. g., if your Ubuntu(/Shim) entries are number 0002 and 0003, you can remove them by typing:

    sudo efibootmgr -b 2 -B
    sudo efibootmgr -b 3 -B
