UPDATE: So after I broke grub, I tried reinstalling Fedora. Now windows has disappeared from BIOS
EDIT: So after all that, I was able to reinstall windows and download Macrium reflect + my backup. First time I tried to recover it, it failed for some reason, but the second time around I was able to restore it successfully. I'm now back where I started, thank you everyone!
I'm not done with Linux yet, but I think I'm going to try and run it in a good VM for the time being. When I'm done with classes, or when I get a separate device, I will give it another go.
Yesterday I could at least change the order in the BIOS to boot windows. Now I can't even do that.
I think when reinstalling, I must have overwritten something (the EFI?). I saw some other people that had a very similar experience, and the advice was to reinstall Windows. I'm currently downloading Windows installation media on another computer and I'm going to try and reinstall windows now.
This just keeps getting worse and worse, and thank you for the help while I struggle through this.
Jesus, stop. You probably only removed the boot entry, happened to me before. Download Windows ISO, put it on a pendrive, boot into it and navigate to the terminal. Then look up a guide on how to restore the boot entry, should be just couple of simple commands and you're done.
If you are too lazy, at least boot into Linux, mount the Windows drive and back up your stuff.
Even this is not necessary, you can repair it from Fedora itself, if you know your way around efibootmgr. Unfortunately given the rest of the posts so far, I'm afraid that's not the case
Thank you! This is completely on me for just rushing ahead and accepting the loss, but I'll save this for if I run into this again. The only option on the recovery screen I didn't try was the terminal.
