Comment 56 for bug 1899308

@ everybody,

In the light of the lasts findings, questions and suggestions, I did some more tests, this time with yesterday's Xubuntu Groovy iso file, that failed booting yesterday.

I think I started testing the cloned USB drive in the Lenovo V130 (which worked), and continued testing in the HP Elitebook 8560p.

Anyway, today I started with a cloned drive (without prior wiping) and testing booting in the HP Elitebook 8560p.

- Successful boot first time, and an ext4 partition was created
- Failed boot after that: the drive was not recognized (could be repeated)

Then I created a 'nopersistent' drive with mkusb-plug in the same drive (without prior wiping) and testing booting in the HP Elitebook 8560p.

- Successful boot first time. No ext4 partition was created
- Successful boot after that (could be repeated)

I conclude that the crucial thing is the existence of the ext4 partition (and maybe other things associated with it - corruption, backup gpt table at the tail end of the drive ...)
