system does not boot

Strike0 · 2023-09-19 10:27:58

No, just boot the ISO and use a partitioning tool (e.g. gdisk/cgdisk) to change the type to EF00/Efi system. Then try booting it again.

changed it to EFI system but it does not boot nonetheless

Hm, too bad. Perhaps the grub-install did not work originally, in this pic, if states (hd0,msdos2). That reads fishy, because you clearly use gpt now.

Try to repeat the grub-install command you used, after chrooting again.

did that but it still shows hd0, msdos

As Strike0 suggested, the partition type is wrong.
may I ask where did you find it? Could you elaborate on this matter please?

Seth found that by looking the output of 1 which you then changed to the correct EFI system type (2). The partition type is independent of the used filesystem, it denotes what filesystem the partition is supposed to contain. A system booting with UEFI must exactly have one active EFI system partition (3), a system booting with legacy Bios must have one partition marked as "bootable".

And I suppose grub-install did not complain with errors.(?)

Frankly, I'm at a loss. Have you looked in the bios, if there is an option to explicitly set it to UEFI?
I'd check that and if it does not help/is available, try to install grub without chrooting next. See the note, but we have to recheck how to excute it.

From reading the note I would currently: mount /dev/sda2 root to /mnt, next mount /dev/sda1 to /mnt/boot and execute the install with

grub-install --target=x86_64-efi --efi-directory=/mnt/boot --bootloader-id=GRUB --boot-directory=/mnt/boot --removable --recheck

But I can't remember right now, if --efi-directory is supposed to be /boot or /mnt/boot in this exception of installing outside the chroot.

https://imgbb.com/fC0ZZxV is from the install iso
https://0x0.st/HOOx.txt says the partition is GPT

Run the command in #31 and post the complete output.
In doubt you can log it into a file in a "script" session.

Installing for x86_64-efi platform

Installation finished. No error reported.

seth · 2023-09-19 12:23:03

So is grub now found?

It did work!

Now, have you guys got any idea why the usual grub-install did not work if it did work a week ago on the same machine with the same disk?

and the interesting thing is that my /dev/sda1 is not partitioned as EFI System and it still boots.

Don't do that. https://wiki.archlinux.org/title/Genera … es#Bumping

If "grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub" was literal (nb. the capitalization) and possibly you did this outside a chroot, there're obvious differences between that and the ultimately succesful command.
We can't tell you what you did wrong 10 days ago, evidently "something"

Yes, now I did that outside of chroot, but those 10 days ago I did this while chrooted:

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub

and I was able to successfully launch the system.
