EDIT: the directory and the boot.mod file exist… odd
However when I try to list it in grub recovery I get error: unknown filesystem. This error is displayed even after other files are listed successfully.
The partition is xfs
EDIT: An observant reader will note that the list command I ran at the grub rescue prompt didn’t use the correct partition! I should have run ls (hd1,msdos1)/grub/x86_64-efi/boot.mod not msdos2. Either way it can’t/won’t read that file.
