GRUB disappeared after system mantainance

Hi @anon58427774,

Sounds to me that you need to reinstall GRUB from chroot environment.

How to chroot

  1. Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.

  2. Write/copy/dd the ISO to a USB thumb drive.

  3. When done, boot with the above mentioned USB thumb drive into the live environment.

  4. Once booted, open a terminal and enter the following command to enter the chroot encironment:

manjaro-chroot -a
  1. If you have more than one Linux installation, select the correct one to use from the list provided.

When done, you should now be in the chroot environment.

But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart.

Reinstalling grub from chroot environment.

Once in the live environment, you have to reinstall GRUB. To do so, run the following:

update-grub

When successfully completed, exit the chroot environment:

exit

Followed by rebooting and seeing if it worked.

If it did, feel free to heap on the praise. If, however, it didn’t, well, then I’m not here. (Mostly, I suspect, I’ll have to be off then.)

Hope this helps!
