It’s possible to use efibootmgr to re-add the firmware entry for Fedora, even from a rescue disk. It might be easier, however, if your BIOS has a way to choose a new boot entry and to select the Fedora grub2 EFI executable, so you can just boot directly into Fedora and run efibootmgr from there. You certainly don’t need to reinstall the whole OS. It’s just a couple bytes in the hardware’s firmware. -- Jonathan Billings _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
