Hi I think this is the same problem that some users of debian-live has found. This project builds amongst different outputs an usb-hdd image but during the build if one have replaced classic fdisk with gnu-fdisk it fails.
During build it mounts an zerofilled image losetup -f binary.img and then it checks it with fdisk -l -u with gnu-fdisk we get Error: Unable to open /dev/loop0 - unrecognized disk label. but with classic fdisk it gives: The size and the CHS of the image, and complains of the lack ot partition table just as it should. regards //Peter -- /bitrunner/ *0708-460260* Andra LÄnggatan 28 41327 Göteborg Sweden
