Bruce, I've given it a spin but no go. When I attempt to boot from it I get a kernel panic. When I boot from the host and check the device with gdisk It returns:- GPT fdisk (gdisk) version 0.8.8 Warning! Disk size is smaller than the main header indicates! Loading secondary header from the last sector of the disk! You should use 'v' to verify disk integrity, and perhaps options on the experts' menu to repair the disk. Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. Warning! One or more CRCs don't match. You should repair the disk! Partition table scan: MBR: protective BSD: not present APM: not present GPT: damaged **************************************************************************** Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk verification and recovery are STRONGLY recommended. **************************************************************************** I've tried all the gdisk suggestions but to no avail. It's an older version of gptdisk than the current BLFS version; I don't know if that matters. The partition table looks OK:- Disk /dev/sdc: 15240576 sectors, 7.3 GiB Logical sector size: 512 bytes Disk identifier (GUID): 1A6C8E1A-791C-4407-A0CD-CDEFC9989092 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 15265750 Partitions will be aligned on 2048-sector boundaries Total free space is 6875061 sectors (3.3 GiB) Number Start (sector) End (sector) Size Code Name 1 2048 4095 1024.0 KiB EF02 BIOS boot partition 2 4096 8392703 4.0 GiB 8300 lfs-usb Any ideas? The host is an old Toshiba Satellite, running 64bit Linux Mint. It seemed sensible to try it on something that wasn't related in any way to BLFS.
