Hi, out of curiosity i compared systemrescuecd-x86-3.2.0.iso and debian-wheezy-amd64-efi-test5.iso.
One important difference is that systemrescuecd has no MBR or GPT. The whole system area is filled with zeros, where test5 is generously equipped with hard disk partition tables. I see MBR, GPT, and APM. BIOS should ignore this region if it is presented on CD. I am not sure what EFI is supposed to do in this case. In any case, test5 looks as if it could be hit by the bug from 1.2.4 that is fixed in 1.2.6. The MBR bears a single partition of type 0x00. (I currently riddle how this could happen. The known bug zeroized partion slots 2 to 4.) Proposal for a test: Overwrite the first 32768 bytes of debian-wheezy-amd64-efi-test5.iso by zero bytes. Burn it to CD and try to boot from it. If this succeeds, then Steve could build test6 with xorriso-1.2.6 and i would have a look at it whether it is more plausible as disk image. As soon as this is achieved, one could retry booting the improved image from CD, despite its partition table equipment. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
