[Bug 1905491] Re: Recent (Nov 2020) ISO copied to USB Drive cannot load

[Steve Langasek]

This looks like an error in the tool you've used to write the image to
the USB disk, not a bug in the image.

As far as I understand, Startup Disk Creator is not software that's part
of Ubuntu; so closing this bug rather than reassigning.

Title:
  Recent (Nov 2020) ISO copied to USB Drive cannot load

Status in casper package in Ubuntu:
  Invalid

Bug description:
  2020-11-24 10:58 GMT Downloaded ubuntu-20.10-desktop-amd64.iso  via
  torrent

  Used Startup Disk Creator on two previously working 4GB USB sticks

  Both Print GRUB  then  "Error can't find grub_platform"

  Show a boxed Ubuntu Studio but no live OS is loaded

  Tried on two BIOS based 4core/6core AMD computers - same outcome.

  USB stick can be used to mount ISO ->   /boot   contains some grub
  files

  
  Problem is identical on  :-
  ubuntu-20.10-live server-amd.iso
  ubuntu-20.04.1-live server-amd.iso
  kubuntu-20.04-desktop-amd64.iso

  I suspect that a change in the creation of these ISOs is causing NON-
  UEFI machines to fail to load Grub2 correctly.
