Did you install Fedora on the same physical drive as Windows? And was a 2nd drive involved in the installation? And what do you get for 'efibootmgr -v' ? There are some edge cases where you get what you describe, and it suggests the initial grub2-mkconfig at the end of installation didn't find the Windows boot loader. There's also a gotcha with recent installations of Windows 10 which automatically encrypt the Windows installation and sequester the encryption key in the TPM. The only way the key is revealed is when measured boot indicates the system isn't compromised. The problem is that booting shim+grub results in measured boot failure when choosing the Windows boot entry, and while Windows does boot, it also asks for the recovery key for the drive. The alternative is use the firmware's built-in boot-manager (boot selection menu) to choose Windows. On my Lenovo laptop you can get to this menu with F9 (or press enter at the logo screen, which gets you a function key lookup chart superimposed on the splash, which shows F9). And from there choose the Windows Boot Manager. -- Chris Murphy _______________________________________________ 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 on the list, report it: https://pagure.io/fedora-infrastructure
