Installation Guide/Configure GRUB
- To enable the GRUB bootloader at boot-time, install it to the boot disk, and generate an appropriate boot menu file: grub.cfg in the conventional location:
# grub-install /dev/sdX # grub-mkconfig -o /boot/grub/grub.cfg
... where '/dev/sdX' in most cases, is the same disk that you mounted in the pacstrap step, typically the only physical disk in the computer. Note: this is NOT the '/dev/sdXN' partition that you mounted on /mnt (e.g. /dev/sda1), but the physical raw disk root itself (e.g. /dev/sda).
