Failing to be able to boot from a system built with daily 22.04 from 2022-02-26

[Michael Lueck]

Greetings Xubuntu developers,

I had not pulled a daily ISO since 2021-12-20. I applied about a month or so worth of updates all at once via Synaptic. I ended up loosing Nvidia display, it stalled, so I ended up having to force 
packages to finish applying once I could get video back via: sudo dpkg --configure -a

Also I needed to switch to a non Debian / Ubuntu based distro on the test machine to prove out if an unrelated defect was coming from Debian / Ubuntu origins only. I needed to stick with something 
Xfce desktop based, so I selected Manjaro manjaro-xfce-21.2.2-220123-linux515.iso  I had to install that several times in order to get it to boot from the hard disk. I finally had to have it do its 
own partitioning... not manually re-using the partitions Xubuntu had created.

Coming back to yesterday's daily Xubuntu 22.04 ISO, I still cannot get the system to boot from the hard drive.

I have the motherboard set to EFI boot mode.

I have wiped the partitions again, this time with the Xubuntu daily DVD. As a first partition I create a 500 MB EFI partition. The rest of the drive I want as a XFS formatted / (root) partition.

The load finishes, the installer ejects the DVD, it still does NOT display the text to press any key to restart the system (defect reported earlier by me), and then the system goes through the BIOS, 
lands at a black screen with blinking cursor, forever.

I booted back off the Xubuntu installer DVD. I inspected the partitions with Gparted. That raised an error that it wanted the mtools p[package added to be able to interrogate the EFI partition 
properly. I exited GParted, added that via apt-get, restarted GParted, no more error. (Note to add that to the package configuration of the LiveCD mode.)

The Xubuntu installer marked the EFI first partition only with flag msftdata. I added the flag boot, which also automatically added the esp flag, and removed the msftdata flag. I exited the LiveCD 
mode. The system still refuses to boot from the hard disk... after BIOS POST, just a blinking cursor in the top left corner on a black screen.

Any suggestions, please?

I am thankful,
