Your assumption is correct. My desktop PC is an HP EliteDesk G2 Mini with two USB drives (one HDD, one SSD) typically hanging off of it. Both external drives as well as the internal drive are bootable. Each drive has its own ESP. No problem booting one of the external drives on any of my laptops. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-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/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
