1.5.1 Bootloader

In the main repository, there is efibootmgr and grub to serve as bootloaders. efibootmgr can be used as a standalone bootloader, or can be used to install grub in a UEFI environment. efibootmgr is needed unless you are using a device without UEFI support (or you really want to use BIOS for a reason).

1. GRUB BIOS installation

   cpt b grub && cpt i grub
   grub-install --target=i386-pc /dev/sdX
   grub-mkconfig -o /boot/grub/grub.cfg
   

2. GRUB UEFI installation

   cpt b efibootmgr && cpt i efibootmgr
   cpt b grub && cpt i grub
   
   grub-install --target=x86_64-efi \
                --efi-directory=esp \
                --bootloader-id=CarbsLinux
   
   grub-mkconfig -o /boot/grub/grub.cfg
