efi(8) just manipulates EFI variables in NVRAM: it shouldn't make any changes
on a disk. Plus, those entries don't look right; they say:

Boot0004 == partn. 1, start = 0x800, size = 0x6400000
Boot0005 == partn. 1, start = 0x800, size = 0x19000

You shouldn't have 2 partitions starting at the same location, with 2 diff.
sizes and UUIDs. How'd this happen?

Or, a USB-stick? Or, add entries in the BIOS? With UEFI, these things are
a lot less catastrophic :).
