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

[Michael Lueck]

All right, significant more testing... about 10 drive wipe reloads of
this test system. Finally I got the Xubuntu DVD from this past weekend
to produce a bootable HDD.

Some of the failed attempts were:
BIOS UEFI enabled
gpt partition table
500MB EFI partition first
All the rest XFS partition

BIOS UEFI enabled
gpt partition table
All the drive XFS partition

BIOS UEFI enabled
Let Xubuntu auto partition the entire drive... some sort of ext4 scheme, which also failed to boot.

Works - produces booting system
BIOS UEFI disabled
msdos partition table created in Gparted
All the drive XFS partition created in Gparted
The installer warned this may not produce a bootable system.... on the contrary, this finally does boot properly!

Shall next try:
BIOS UEFI disabled
gpt partition table
500MB EFI partition first
All the rest XFS partition?


I thought for sure I had success before enabling UEFI boot in the BIOS / having a gpt partition table and EFI partition... back in December. I am really puzzled why the configuration is now giving me a fight. Too late to go back now.

At least the test system boots again. I can continue on with other beta
testing. Please advise what combination you would like me to try to
modernize the drive partitioning beyond an msdos partition table.

Title:
  Jammy Live installer not producing booting EFI 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. :-(
