This gives me a switch root error and stops at the emergency mode prompt #.

You're missing all the parameters to the kernel that tell it where the root is.

How do I get my server to boot again ?

From your other email:

> grub2-mkconfig -o /boot/grub2/grub.cfg

That's the wrong place for an EFI system. You need to mount the EFI partition (probably /dev/sda1 in your case) at /boot/efi and the grub.cfg is in /boot/efi/EFI/fedora/.
