Hi,
I had a working dualboot setup with GRUB on my old System.
After upgrading to a new PC, there is no GRUB entry in bios.
I got myself a new PC.
On my old System I had a dualboot setup with Windows10 and Manjaro (each OS on a seperate SSD).
I took the drives, and put them into my new System.
After starting up the system for the 1st time, windows was running some kind of repair mode. After finishing, I landed in windows10, and in windows everything is working as expected.
In my EFI bios, I can’t select GRUB as boot-option (it’s missing).
I created a live usb with manjaro, and booted from that:
- There was a option (before actually booting to manjaro) that was called “detect efi bootloaders”.
- After clicking that, I could select my grub from the list.
- Grub started successfully, and I could successfully boot into my Manjaro System from there.
So my question is: How do I get GRUB to show up in my EFI bios, in order to select it as boot-option?
I read about using efibootmgr to create an Item for GRUB but I am not sure how exactly to use it.
My grub is resent in /boot/grub/ and it is working appearently, but somehow just not showing in bios.
Any help to fix this would be highly appreciated!
EDIT: I tried following the steps provided at the manjaro wiki GRUB/Restore the GRUB Bootloader - Manjaro
But failed at running manjaro-chroot /mnt /bin/bash
$ manjaro-chroot /mnt /bin/bash
mount: /mnt/proc: mount point does not exist.
==> ERROR: failed to setup API filesystems in chroot /mnt
EDIT2 : Managed to fix it with the instructions from the manjaro wiki.
- Reinstalled grub
- updated grub config
now I have a boot-entry in my bios, from which I can start grub, and choose whether to boot into manjaro or windows.
