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

[KOLANICH]

** 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-16.04-desktop-amd64.iso
  and then
  show
   and got
  >Model:  (file)

  >Sector size (logical/physical): 2048B/512B

  (I don't know why it writes 6083MB)
  
  fdisk --type=mbr -l ./kubuntu-16.04-desktop-amd64.iso
  gives
