Installimg W7 64bit & W8.1 64bit on seperate SDD'

Hi All,


I know that I can install W7 & W8.1 on separate partitions on a Hard Drive, but I just want to pose the question is it possible to install W7 on a SDD and w8.1 on a separate SDD on a PC system in effect having two operating systems on separate Drives, is this possible to achieve ?.
Look forward to hearing Your views on this matter.


Many Thanks
