Daniel, This may be too late but. Do you want to do an upgrade or have a key for a fresh install? As far as I know and have limited experience with is changing BIOS means a fresh install. So just make sure you have the latest Windows 10 build and do a clean install. When it asks for the key, put in your valid Windows 7 key and it should activate. The build has to be at least the Nov. build. I have done about 10 installs that way and it has worked fine.

Did in-place upgrade with the EXE. After it rebooted into the WinPE install environment, I shut down and changed BIOS to UEFI and deployed Win10 with MDT. It's not activated. Looks like you have to go through the entire Win10 upgrade. =( *shakes fist at Microsoft* Why you gotta make stuff complicated.

The only way I've seen/read that this can be done is to do an upgrade - get that key generated where it's stored on Microsoft's servers, then do a clean install. At which time the machine will check back into the servers and pick up it's generated key. You have to hop twice through the server process and actually complete the install as I understand it.
