I recently installed Fedora on a separate drive, but now my Windows drive is missing from the boot manager. The Windows drive still shows up in the file manager on Fedora, so I'm hoping someone can help me restore it to the boot options. Any advice on how to fix this?

Try accessing your BIOS by repeatedly pressing the designated key (like F11 or Delete) when booting up. Make sure your Windows drive is visible there. You can also create a Windows boot USB from your Fedora setup to try and repair the Windows installation.
Your Windows drive might just be hidden in the boot menu. After entering the BIOS, go through the list of bootable devices to check if it’s been moved around. If it’s there, you may need to edit the bootloader from your Fedora installation to include it back into the boot options.
Just a heads up, make sure it’s not a case of your drives being on the same RAID or something like that. You mentioned it's a separate drive, which is good. If it’s showing in BIOS but you can’t select it as a boot option, that’s strange. You could look into tweaking the bootloader settings on Fedora to include the Windows drive.
First, check your GRUB configuration file to see if it’s been updated correctly. Sometimes when you install a new OS, it can mess with the boot settings. Also, Windows 11 does have a tendency to drop out of the boot menu for some users, so it might not even be related to your Fedora installation.
