Correct. But we are talking Windows 7 here. It will lose it's activation for
sure, but as far as my experience goes you can always reactivate Windows 7
with the same keycode (unless it was a counterfeit one and is intentionally blocked).
As a last resort MS offers a phone dialog system that has always worked for me.

This is actually the bigger of the two obstacles. If the original installation is
MBR booting, I don't know of a way to convert it to EFI.

If you happen to have some genuine not "OEM" Windows 7 install medium
*and* your original key, you should be able to do a fresh installation and
complete activation - via phone if necessary.
