I've looked everywhere about this to no avail, the solution is either to just reinstalling windows (which is not what I'm about to do) or so convoluted with techy stuff I don't understand. Now the problem is that for some reason, windows boot manager is on an empty drive that I've always had empty, but I keep windows on my m.2 SSD, that wasn't what I originally installed Windows on, but I've since wiped the drive it was and it doesn't require that.
