A friend of mine wants to upgrade home to Pro. The machine they have came with Home pre-loaded and comes with the full version should you want to re-install.
The problem is the Pro disc only recognises half of the drive! If you use the original home disc it sees all the drive?
If you boot to the Pro disc it goes all the way through set-up and you are displayed with the partitioning screen but only half the drive. Boot to the home disc and all is there.
BIOS is set to auto and recognises the make and size.
