How To Fix Grub With EFI Boot?

This will fix on a standard installation, if you do manual partition, ask at the forum!

Boot up with our LiveIso.

mount System to /mnt

You need to know which device is the right one check with sudo fdisk -l

sudo su

(/dev/sdXn should be replaced with the right device information)

mount /dev/sdXn /mnt >> / root partition

mount /dev/sdXn /mnt/boot >>> /boot partition

mount /dev/sdXn /mnt/boot/efi >>>>> the EFI-boot (fat) partition

arch-chroot /mnt


BUT that grub is not in the boot list can be caused also by EFI-Boot-Settings not related to Grub and Antergos then, so re-/installing-/building grub may not solve your problem…

You can also make shure to get second (dual boot) installation rechecked and put into grub boot menu:

(as root also) If you have dualboot os-prober may takes a long long time to work, the trick here is to mount all other partitions, before using it.

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


Reinstall grub:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Antergos-grub



For legacy (bios) systems go here:
