Re: Grub not loading on UEFI/GPT install

The capitalisations are not important.

Is there a way I can try to launch arch (or gummiboot) directly from the motherboards EFI shell?

Re: Grub not loading on UEFI/GPT install

Are these paths case-sensitive?

vfat, as for ESP,doesn't matter the letter case.
The way to boot a system is to match three conditions.

• The boot loader/manager need to find the partition and correct path where the kernel reside (ESP is defined by the BIOS, less issue)

• The kernel line needs the details of which partition is the system root

• The /etc/fstab needs to contain the line of which partition to mount as root

One of these is incorrect and we fail to boot. Commonly all of these are defined by UUID, so we need to check whether these UUID are matching.

Developers invented UUID, because they can't guess what name you'll prefer, but, believe me, partition names are the easiest way to remember and handle

Re: Grub not loading on UEFI/GPT install

Unfortunately I'm still having no success. I followed the instruction in this thread (post 51) but the result still hasn't changed:black screen with blinking cursor when I select the boot entry. But: after following the instructions and running efibootmgr -v I noticed that the entry had periods between each character for the kernel arguments. I removed the character conversion step, and that fixed the periods, but neither boot entry works. Something strange is going on.

I've just ordered a new motherboard that I'm hoping will solve my problem (this MSI has not been all that great). It's an ASUS and should be here in a few days, so we'll see if it improves things.

Re: Grub not loading on UEFI/GPT install

It's an ASUS

Oh dear...

I have seen problems on these forums (and also on the Debian forums & linuxquestions.org) with ASUS motherboards and Secure Boot -- the only way of disabling it on some ASUS motherboards is by returning it to the manufacturer.

Maybe you should contact ASUS and clarify this issue with them.

The Arch live .iso will boot up with Secure Boot enabled but your installed system will need it disabled unless you sign your kernel & boot loader/manger with self-generated keys that you have also entered into the frimware (again, this may not even be possible with ASUS hardware):
