Ok let me explain what I would like to do in simple terms,
Currently I've got Windows 7 Home Premium installed on my laptop. My goal here is to do two things :
1) I would like to create a separate partition and install Windows XP beside Windows 7.
2) I would like to somehow "hide" my whole Windows 7 partition and have my system automatically boot into XP when the computer is turned on.
The reason I want this is simple, I want to prevent certain relatives from seeing my sensitive data on my Windows 7 account. I would also like to be able to prevent them from knowing that I've got Windows 7 installed in the first place, that's basically what it all comes down to.
How would I go about doing this ?
