i have 7 pro on my main machine, and want to take it to 8.1 pro. the current os is on the mechanical boot drive, but i have added an ssd to the machine, and would like 8.1 to establish itself there. during the upgrade will i have an option to install it to the new, blank, formatted ssd, or must i forego the upgrade path and do a full install to the ssd? thanks, zz03
