The options are: UEFI Boot: Windows Boot Manager The bios option only talk about updating the bios from options if you can't do it from windows. The exact same USB boots fine from the Dell 3070 units. Also my Dell desktop has no problem seeing the USB and booting from one that has grub4dos, but it does show up under a regular USB option in contrace to the UEFI USB.

The user has done that, but the exact same USB Flash that boots fine on a 3070 doesn't show up as an option on the 3080. He can take a hard disk from a 3080 machine, install it in a 3070 machine, boot from the exact same USB on the 3070, and create and image with the 3070. The exact same USB does not show up on the 3080 as a boot option. Yes, it is not currently an EFI Flash so would not show up as a UEFI Flash boot option, but it also doesn't show up as a regular USB boot option. You seem to be stuck on harping about turning off secure boot, but that has been done with no problem. > > — > Jonathan Billings _______________________________________________ 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
