Hi,
... and if the erasure of the partition table entry helps, would it then
also help if that entry's partition does not start at LBA 0 ?
Change bytes 446 (dec) to 461 (dec) from (in hex):
80 00 01 00 01 01 12 4f 00 00 00 00 40 0b 00 00
to
80 00 02 00 01 01 12 4f 01 00 00 00 3f 0b 00 00
"02" = Sector 2 = LBA 1.
"01 00 00 00" = LBA 1.
"3f 0b 00 00" = bloc count 2879, rather than 2880.
Reasoning:
It would make a nice endless loop if EFI dives into any partition
and looks for sub partition tables. The one in GRUB's efi.img refers
to itself.
DVD might be immune because EFI does not do this diving when it finds
the partition by the El Torito boot catalog.
Have a nice day :)
