GPT BIOS failed to find Arch installation

view story

https://bbs.archlinux.org – When I boot nothing happens. It takes me back to boot menu and no grub is loaded.What boot menu? The boot menu where it says "GRUB 2.00"? That's GRUB. You probably just forgot to generate a grub.cfg, or you should have used "grub-install [...] /dev/sdb" instead of /dev/sda (if Arch is on the second drive).Note: Change /dev/sda to reflect the drive you installed Arch on. Do not append a partition number (do not use sdaX).Speaking of which, are there any other hard drives in the machine?And I hope you didn't mount the 2 MiB partition as /boot during the install proc (HowTos)
