So I managed to get grub installed on a uefi system. When I rebooted 
with out unmounting the live cd it took me strate to the arch login 
screen. I installed efibootmgr befor installing grub because when I did 
it the first time it said it needed that package. 
There are the commands I used. 
grub-install --target=x86_64-efi --recheck /dev/sda 
grub-mkconfig -o /boot/grub/grub.cfg 
It said there were no errors and it went well until I unmounted the 
iso. It took me to this efi interactive menu. Being blind I scanned it 
with OCR and found this shell> prompt at the very bottom. Did I do 
something wrong here and how could I fix this on the next install. 
Someone told me about the udate-grub command.
