MS-Windows interacts with UEFI differently, and it can lead to such
problems, but if that's not the issue than it could be that BitLocker is
running interference because you're running under a different CPU or EFI
signature (whatever it relies on to detect hardware changes, I don't
recall off-hand).

You'll probably just have to work with copies of the data and then take
advantage of the opportunity to install MS-Windows in a virtual machine
so that moving to other hardware in the future won't be a problem.
