[Bug 2026336] Re: Ubuntu MATE 22.04 ISO installer detects laptop boot mode wrong (BIOS vs UEFI)

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. Please execute the following command only once, as it
will automatically gather debugging information, in a terminal:

apport-collect 2026336

When reporting bugs in the future please use apport by using 'ubuntu-
bug' and the name of the package affected. You can learn more about this
functionality at https://wiki.ubuntu.com/ReportingBugs.

( Are you sure you weren't reading an expected WARNING message (may not
boot) as if it was an error message?  It's also possible to get an
actual error message because you wrote the ISO differently to the method
intended for installation media (which can cause the installer to
wrongly calculate its an EFI machine due to ESP existing on installation
media), but we can't currently know as you didn't file report from your
actual media or install & thus no logs are available )

Title:
  Ubuntu MATE 22.04 ISO installer detects laptop boot mode wrong (BIOS
  vs UEFI)

Status in ubiquity package in Ubuntu:
  New

Bug description:
  I booted the ubuntu-mate-22.04.2-desktop-amd64.iso image on a non-UEFI
  laptop.

  After the partitioning phase, I got an error message of a missing EFI
  system partition.

  This error message is erronous, since the laptop boots only in BIOS
  mode.

  Grub is still installed correctly to MBR.
