[SOLVED] Changed motherboard - problem with boot (UEFI)

Hello,

I have Lenovo T470p and after some time motherboard went into Silicon heaven (= broken). MB was changed for new but now I have problem with booting into my system - that means I'm not possible to boot into my system I don't see Grub menu. In Boot menu I see my SDD but if I choose it it's switched into black screen, happened nothing and after some while I can see Boot menu again.

In UEFI I set "UEFI Only" as I did last time during installation. But now I don't know what to do next. IMHO is problem in UEFI/Grub loader, but not sure what to do or fix.

Can I ask you for help, please?

Re: [SOLVED] Changed motherboard - problem with boot (UEFI)

You likely need to boot off the Arch installation medium, chroot into your system, and reinstall GRUB.  If you're EFI with GRUB then boot entries are stored in your system's non-volatile firmware.  This is separate from the harddrive, it's on the mainboard - which you've said you've replaced.  So that seems like a likely culprit.

@headkase: In fact I tried that but by mistake changed grub-install for grub-mkconfig. But your "kick" helped me. Many thanks for your answer. ;]

My solution:
1. Chroot into your system
2. Type command:

grub-install

3. reboot
4. voila you are in your system ;]
