Hey there,

I have a dual-booted environment of Windows 8.1 and Fedora. I recently decided to run the internal Fedora update to upgrade from version 20 to 21.

When this completed, I was able to boot into Fedora fine, but could no longer boot into Windows. The option to boot into Windows had never worked in my Grub2 menu, but I had been able to press 'c' and then type 'exit' in order to get to a menu that allowed me to boot into Windows.

After the update, typing exit fails, and returns me to the Grub2 menu. I've played around with a number of different methods for trying to link the Windows option with the correct location, but so far I've had no luck.

I have some beginner experience with Linux, but am not by any means an expert. Here are some snippets from my terminal that might help. Please let me know if there are any additional resources that you need to properly assess the situation!

fdisk -l

parted -l


[root@localhost ~]# efibootmgr -v

Let's see the output of efibootmgr -v from Fedora please - you can just paste it into your question and mark as preformatted text - no need for a screenshot to share text.

Great, now try efibootmgr -n 0000;reboot

That command booted me into Windows, which is fantastic! I'm guessing that wasn't intended to fix the boot manager, because it's still only linked to Fedora.

Not sure if my comment failed to submit last time, but that command booted me into Windows successfully. I'm guessing it wasn't meant to fix my boot manager though!
