GRUB/EFI problem, can't boot normally

Support

Hi,

I’m having problems booting my laptop since a few days.

It boots straight into the GRUB prompt. If I boot using a Manjaro USB key and choose ‘Detect EFI bootloaders’ I get to see this:

If I choose the last option ((hd1,gpt3)/efi/Manjaro/grubx64.efi), my system appears to boot normally. Interestingly the entries of Ubuntu are still present, which was installed on this machine before switching to Manjaro.

If I check the boot devices in my BIOS, ‘Ubuntu’ shows up, but not Manjaro.

Running ‘efibootmgr -v’ reveals this:

So it appears my BIOS is trying to boot Ubuntu, which isn’t installed, hence it ends up in the GRUB prompt.

How do I fix this mess?

  • remove the ubuntu entry (which isn’t installed anymore):
# efibootmgr -b 0000 -B
  • boot from manjaro usb
  • manjaro-chroot into your existing installation
  • reinstall grub

The wiki has a detailed step-by-step:

Thank you, that helped me fix it.

What’s strange though is that the Ubuntu entry comes back after each reboot. How can I get rid of it for good?

You can try removing it directly in your UEFI/BIOS, other than that :man_shrugging:

I did it by mounting my EFI partition to and deleting the ubuntu directory there.
All good now, thanks again!
