After installing Arch I installed grub with these commands:
pacman -S grub
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub --recheck
grub-mkconfig -o /boot/grub/grub.cfg
Now the grub menu appears and I can choose Arch Linux. However, when I choose to boot in Arch Linux via grub I am greeted with this:
Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to try again
to boot into default mode.
Cannot open access to console, the root account is locked.
see sulogin(8) man page for more details.
Press Enter to continue.
Pressing enter results into the same message with the added line:
Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)
My EFI boot menu still works fine, so I'm still able to login to Xen.
I have also notice a failed message when trying to boot into Arch Linux:
[Failed] Failed to mount /proc xen.
