I’ve installed Antergos on a dual-boot (w/ Windows 8 ) system, Windows on one SSD and Antergos on a second SSD. The installer completed & appeared to run smoothly, but when I reboot, instead of the GRUB menu, I get a GRUB prompt. I’ve tried reinstalling GRUB using the directions on the Arch wiki, but when I do I get the following output:
[[email protected] ~]$ sudo mount /dev/sdb1 /mnt [anter[email protected] ~]$ sudo mount /dev/sda2 /mnt/boot/efi [[email protected] ~]$ sudo arch-chroot /mnt [[email protected] /]# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=antergos Installing for x86_64-efi platform. EFI variables are not supported on this system. EFI variables are not supported on this system. Installation finished. No error reported.
I’m positive that this machine supports UEFI. What could be the problem?
