Switching from Intel to AMD: Unable to boot

Framework Laptop 13 Linux
1

I’m upgrading my Framework 13 12th Gen Intel Core to an AMD 7040 mainboard, but when I install the new board, my computer fails to boot. I suspect it has something to do with my bootloader, but I’m not sure what I need to fix it.

Here’s the basic output of fdisk:

Disk model: WDS100T1X0E-00AFY0
Disklabel type: gpt

/dev/nvme0n1p3 135268352 1953523711 1818255360  867G Linux filesystem

And the output for efibootmgr:

The power light blinking indicates that the hardware diagnostic completed successfully. I’ve poked at the firmware’s boot options but everything looks right to me - the motherboard can see the RAM (1 x 32GB DDR5-5600 SO-DIMM) and hard drive, and I can boot into a live USB, just not my regular system. Secure Boot is disabled.

Does anyone know what next step I should take here? Thanks in advance!

My friend who I got the AMD board from has let me know that the boot entries are stored on the motherboard itself, not in the boot partition. So I’ll need to look at them on the new motherboard via livecd. Probably there’s just no entry for GRUB on there!

Is the laptop plugged in when you’re trying to boot ? There’s a power save option in bios that prevented my system from booting when running on battery after an upgrade.

post (paste somewhere) the contents (recursive) of the EFI system partition.
It really sounds like the EFI firmware is trying to start something that isn’t there.
How the hell did windows get into the EFI boot list? I don’t see a windows partition.

What I’ll try to get you to do is to make grub the default EFI target, which means putting the grub efi executable at /efi/boot/bootx64.efi .

Success! After re-installing the AMD board, I was able to “boot from file” in the bootloader (no idea how I missed this the first time around). And then after linux booted up, I ran sudo efibootmgr --create --disk /dev/nvme0n1 --part 1 --loader '\EFI\GRUB\grubx64.efi' --label 'GRUB' --unicode.

Now to figure out why my computer freezes fully or partially (no wifi and I can’t open menus in hyprland) after I close and re-open it…
