It's a race, 1 out of 10 tries succeeds and the chance that it does is improoved by inserting the usb drive while being in the bios. The F31 grub files i exchanged do not seem to have something to do with it. Could it be a timing issue of some kind? the sooner i hit the boot from usb button, after the stick got inserted, the higher is the propability to start. I think we can rule out signing here as the surface is in none secure boot mode and it starts ( screenshot available). So what else could cause this? best regards, Marius _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
