Hey Dave, I've done a bit of research, and figured out that taking option one; restore to first partition, is the best choice as it only restores drive C, and my valued data is on drive D..
And to my understanding the second option wipes everything and then recreates a single drive (c:\) and the third option wipes everything and then recreates a drive c:\ and d:\
I ran the first option as I was assured by reading other forum threads that my D drive would remain untouched.. The only problem now is that once that was finished I turned it off and on and it went straight back into the Preload Wizard again...
Any ideas on this matter?
