Those implementations I am aware of will skip MBR if protective entry is found. None of them also actually checks partition size. I am aware of one case where incorrect partition size caused problems (libparted, although I think it was caused by vendor patch); neither edk2 not GRUB nor Linux care for it. > MBR partition : 2 0x80 0x07 64 272 > MBR partition : 3 0x00 0xef 336 5760 > MBR partition : 4 0x00 0x07 6096 26708 > MBR partition path : 3 /efi.img > > Isn't 0xee a misnomer now that you decided for MBR ?

EFI does not say anything about other partition types, besides that other partition entries /should/ not be defined. So any additional partition besides protective is strictly speaking against EFI standard. _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org https://lists.gnu.org/mailman/listinfo/bug-grub
