Boot Managers

Genesi OS installs GRUB as its bootloader, with a Genesi-branded theme. It works in both UEFI and legacy BIOS modes (UEFI recommended).

Dual-boot with Windows or another Linux

During installation choose Install alongside (or partition manually) and install the bootloader to the EFI system partition. GRUB's OS prober will pick up other installed systems.

If another OS doesn't appear in the menu after install:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Repairing the bootloader

Boot from the USB, then chroot in and reinstall GRUB:

sudo mount /dev/sdXY /mnt          # your Genesi root partition
sudo arch-chroot /mnt
grub-install /dev/sdX              # the disk, not the partition
grub-mkconfig -o /boot/grub/grub.cfg
exit
sudo reboot
