Hi, my hand made partition 3 fell victim to the deceptions of nested partitions. It starts inside the ISO after the end of partition 2. It should of course start after the end of partition 1.
So this is not the right start of partition 3: > Device Boot Start End Sectors Size Id Type > test.iso1 * 64 1374207 1374144 671M 0 Empty > test.iso2 1297212 1298619 1408 704K ef EFI (FAT-12/16/32) > test.iso3 1298620 15138815 13840196 6.6G 83 Linux By bytes 00 ff ff ff 83 ff ff ff 00 f8 14 00 00 08 d2 00 i get a more desirable result: Device Boot Start End Sectors Size Id Type test.iso1 * 64 1374207 1374144 671M 0 Empty test.iso2 1297212 1298619 1408 704K ef EFI (FAT-12/16/32) test.iso3 1374208 15138815 13764608 6.6G 83 Linux Have a nice day :) Thomas
