MSI Mainboard doesn't see GRUB

My board is a Z370M MORTAR (MS-7B54) by MSI. The grubx64.efi is located under /boot/EFI/GRUB as the wiki suggests if I understand it correctly.
If I reboot I get thrown into the BIOS and no bootable device shows up.

irondude, it is not enough to have EFI-executable on specific place on ESP partition, also you have to put a record for that file to EFI on you motherboard. Or you can use well known place for your EFI-executable how it is works for EFI-bootable removable media. For that you should put EFI-executable under  esp/EFI/BOOT/BOOTX64.EFI (or esp/EFI/BOOT/BOOTIA32.EFI for the i386-efi target)

Re: MSI Mainboard doesn't see GRUB

In chroot when I do:

grub-install --target=x86_64-efi --efi-directory=/dev/sda1 --bootloader-id=GRUB

I get:

grub-install: error: failed to get canonical path of `udev'.

You have to mount the partition and pass the mountpoint as the argument to --efi-directory. There was a similar issue with an MSI board, so I think sincomil's default path suggestion is right on the money, see here as well: https://bbs.archlinux.org/viewtopic.php?id=238572
