** Description changed: I have an old PC with non-UEFI BIOS (coreboot is also unavailable for my mainboard, the bios is updated to the latest (2008 year) version) without GPT support. Some years ago, when support for UEFI and GPT had been adopted in linux distros, troubles with booting from usb flash drive started. I tried a lot of tools (Rufus, Unetbootin, pendrivelinux, dd and startup disk creator), none of them had helped. If I type - parted path/to/kubuntu/iso + parted path/to/kubuntu-16.04-desktop-amd64.iso and then show - I get a message that GPT table signature is found. If I ask parted to treat it as GPT, it says both gpt tables are corrupt. If I ask parted to treat this as mbr, it prints nothing. This could be the cause of non-booting. + and got + >Model: (file) + >Disk path/to/kubuntu-16.04-desktop-amd64.iso: 6083MB + >Sector size (logical/physical): 2048B/512B + >Partition Table: mac + >Disk Flags: - p.s.
