If that doesn't work but that is the issue then the data is still perfectly fine and readable. Unless you had it encrypted, then you're likely slightly fucked, but potentially not.
If unencrypted AND it's just boot files fubared then you can use a recovery program like recuva to scan the drive and recover the files. You'll need a second hard drive of at minimum equal size to the corrupted one to copy the files to.
Fucking efi. Last time I had a boot corruption, I dd'd the boot sector, fixed it, then wrote it back to the disk. Worked like a charm but efi... I set up a dual boot once with it and hoped never to have to dick with it again.
