If you fix the problems before hand Microsoft is running a 90 day trial for win 7 so you could install it before and use the legit key when you get it.
Doesn't Enterprise 90 day trial require a special type of volume activation?

I believe it's similar to Ultimate but with volume licensing so Ultimate key won't work?

Can the installer be made all-versions as others can by removing ei.cfg from Sources?

It would be nice if someone knows for sure.
