Install Bootloader

TIP

When doing disk encryption, finish the steps on the encryption page. It will guide you back to the main installation when needed.

If you don't know which one you should use re-visit Live Setup/Check if booted in BIOS or UEFI

UEFI

pacman -S grub os-prober efibootmgr dosfstools mtools gptfdisk fatresize
grub-install --target=x86_64-efi --bootloader-id=grub_uefi --efi-directory=/boot/efi --recheck
grub-mkconfig -o /boot/grub/grub.cfg

BIOS

pacman -S grub os-prober
grub-install --target=i386-pc --recheck /dev/sdX
grub-mkconfig -o /boot/grub/grub.cfg
