[Bug 1556599] [NEW] ISO images don't have valid partition tables

[KOLANICH]

Public bug reported:

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
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 mbbbr, it prints nothing. This could be the cause of non-booting.
