[SOLVED] Dual boot Fedora and Windows 10. After reinstalling Fedora Windows 10 entry is gone from bootloader.

I was dual booting Fedora 28 and Windows 10. On the boot menu the Fedora kernels were first and the last entry was Windows 10. During the Fedora 29 upgrade something didn't quite work out so I reinstalled Fedora 29. This boots up fine but I have no Windows 10 in the boot menu any longer. I am guessing this was removed when I installed Fedora 29 on the partitions that Fedora 28 was using. I can still see the Windows 10 partitions but cannot figure out where or how to modify the boot menu to point back to the Windows 10 partitions.

Should have YouTubed first... https://youtu.be/iwwRd_oVaJA

That fixed my issue.

Surprised to see you have a Legacy install of windows 10 as it is usually UEFI. I expect running the grub2-mkconfig command would have done the trick. Fedora has a page dedicated to using Grub2, link below. Might be worth bookmarking if you're going to use Fedora.

Most upgrades from windows 7 to windows 10 boot in legacy mode. I have two computers running windows 10 that was upgrades from windows 7 that boot in legacy mode.

Do you have a windows recovery disk/USB?
The long way round would be to start with

Code:

Bootrec /fixMbr

and then go in and update grub from a Linux liveUSB....I think...
