I know, it's not practical for those who only run a laptop, but if a desktop PC is being used, there is usually space somewhere for an extra HD.
My best advise, for those not familiar with doing whole drive backups
, is to only install Win-8/DP on a totally separate drive, with the main drive unplugged during the install. Of course, use a bootable DVD for installing Win-8.
And you don't have to have an open drive bay for that second drive.
A picture is still worth a thousand words. Eh?
