UEFI Laptop Doesn't Detect Bootable Device

20 January 2024, 23:37:39

I'm almost done installing Artix but my Dell XPS 13 (~2019) laptop computer isn't able to detect it on its own.

Current behavior with the USB containing the artix iso plugged in:
1. Laptop boots to the iso launch menu
2. "Detect EFI boot loaders" option finds "(hd2,gpt1)/efi/efi/grub/grubx64.efi"
3. I can boot into the installation that way.

Current behavior without the artix iso available:
1. Boots to an error message "No bootable devices found"

In the F12 menu:
Boot mode is set to : UEFI; Secure Boot: OFF
...
UEFI BOOT:
grub
Linux Boot Manager

Manually selecting either UEFI boot options results in the same error.

I made sure to set the boot partition's label to EFI System (https://wiki.archlinux.org/title/EFI_system_partition) and followed the instructions for a UEFI installation in the installation guide. The deviations from the guide are that I have only 2 partitions - boot and encrypted storage.

I don't know what else to check or look for. I'd really like to solve this issue.
Any advice or pointers appreciated.

That page explains you must have an EFI partition, you say you don't have one? It could be the problem. Before EFI, using BIOS boot, the boot loader first stage was located in the MBR, now it resides in the EFI partition. Rough guide to boot process: HW chip built in software (commonly termed BIOS) > MBR or EFI partition > /boot/somebootloader > kernel cpio or whatever. The usb drive Artix has an EFI partition which is allowing it to boot then it can direct things to the /boot part of your install.

After booting from the cd try running

Code: [Select]

sudo efibootmgr

from the package of the same name and post the output.

I think I have one. I have a 1G partition of type EFI System with a FAT32 filesystem that I mounted on /boot during the installation process.

Double check the UUID 5ad2a131-351c-4af0-bc66-2e59d275e211 is correct.

Other than that if I liked grub I suggest using grub-install again.
Maybe get rid of what I assume is the stale 'Ubuntu' entry. Shouldn't make a difference though?

But imho a better idea, unless you use certain forms of full disk encryption, Is test rEFInd with a USB drive and then once you realise it's better than Grub replace it.
