Seems Xubuntu 22.04 release just cannot detect EFI / UEFI support within the BIOS.

The Ubuntu / Xubuntu ISO DVD's seem to be intelligent enough to boot if
the BIOS has only legacy support or new EFI / UEFI support. Perhaps that
is the area of Ubuntu that has the issue... that the EFI / UEFI detector
fails to detect, so boots in legacy support mode?

For this system, manually partitioning off the Live DVD with Gparted,
msdos partition table, one large xfs partition mounted as root.

Title:
  Jammy Live installer not producing booting gpt partition table / EFI
  partition hard drive installations

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Starting up this weekend's Live DVD of Xubuntu, I am unable to produce
  a system that will boot EFI mode from the hard disk.

  The BIOS is configured to EFI boot mode for the disks.

  This last attempt, I manually wiped the partitions from the drive
  before launching the installer from the LiveDVD.

  Check the partition table
  sudo wipefs /dev/sda

  Wipe the gpd partition table
  sudo wipefs -a -t gpt -f /dev/sda

  Double check that the wipe was successful with the first command, came
  back empty / blank.

  Next started the Xubuntu installer from the desktop icon.

  Chose manual partitioning, created the following
  sda1 500M Primary EFI Boot
  sda2 remainder Primary xfs /

  Once the installation got done, I opened Gparted to confirm the partitions.
  The EFI partition was mounted to /target/boot/efi
  The XFS partition was mounted to /target/

  The EFI partition had boot, esp flags on it.

  I restarted the system, shuts down, exhibits the usual with Jammy
  defect 1962466, I push a key to restart, system goes through BIOS
  screens, then lands at a black screen with blinking cursor in the top
  left corner.

  Getting systems to boot from the hard drive is very frustrating in the
  era of EFI boot. :-(
