I had multiple disks in my PC, one with Windows and one with Linux. The drive with Linux had the boot record I guess; I removed and replaced that one with a new disk and again installed Linux on it (so the Windows disk has been the same the while time), but I can no longer log into Windows while this new disk is installed and the old disk is removed. I can log into Linux while the new disk is installed, and if I swap back to the old disk I can log into Windows.

How do I fix things so I can not into Windows or new Linux while the new disk is installed? I don't mind reinstalling my Linux OS, but I really don't want to reinstall Windows.
