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.

If anyone has other tips, I'd appreciate it :)
