[Bug 1962470] Re: Jammy Live installer not producing booting gpt partition table / EFI partition hard drive installations

[Michael Lueck]

Perhaps has the EFI / UEFI BIOS compatibility changed over time?

Finally boot success using a ThinkPad T540p model 20BE-CT01WW and the
Xubuntu 20220402 Daily jammy-desktop-2022-04-02-amd64.iso

Manual partitions as follows:
sda1  1MB  BIOS BOOT
sda2  500MB  EFI System
sda3  the rest  /  xfs

So seems system specific that Xubuntu is unable to boot from the
internal disk on systems it is able to boot from the LiveDVD, install
without complaints.

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. :-(
