@ 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 ...) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899308 Title: failure to boot groovy daily (again) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1899308/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
