The great thing about UEFI is that it doesn’t involve boot sectors anymore, it’s just files in the EFI volume and entries in the boot firmware. You should be able to go into your BIOS boot menu and choose the Fedora boot entry and it should boot just fine, unless the windows install formatted the EFI volume, but it shouldn’t by default. You can also boot off a live USB and use ‘efibootmgr’ to change the boot order. Be sure to turn off Fast Reboot in the Windows settings. That setting bypasses the normal firmware boot and you won’t see the Fedora bootloader. — 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
