Windows Edit Efi Boot Options How To Use EfibootmgrAll you have to do is move it to the left of 0013 and press Enter. Then make sure it has the EFI version of GRUB boot loader installed. The default target is i386-pc, which is for traditional BIOS firmware. Under the hood, the Grub installer first installs a.efi booloader file to bootefiEFI directory. Usually its named grubx64.efi. Then it runs the following command to add a new entry in UEFI boot menu. And now you deleted a Linux distro but the boot entry is still there.

I installed 5 linux distros on a VirtualBox VM all with UEFI on GPT partitioned drive and didnt have too much trouble. One thing is I cant get the EFI to boot to the grub menu directly, it always boots to the EFI shell first no matter what I try. I ended up deleting the bios uefi setup from my samsung laptop and I can not recover it. I typed the command sudo efibootmgr -b 0 -B (0 being the setup). Does the -b option refer to boot order numbering OR the ordinal numbering BELOW the boot order. Ive tried: efibootmgr -b 000A -B and efibootmgr -b 0006 -B but neither worked. First parameter is to delete; second refers to binary entry. The commands above are not displayed as I wrote it, regardless my escaping tries. Just be aware, that you specify the backslashes twice (to mask the backslashes) when you type the the path after option -l for the efibootmgr command. The output of efibootmgr doesnt match what I see in the grub version I boot from. ![]() Making a donation would incentivize me to spend more time answering questions.
