True, but if he's as non-techie as he claims, he might need a little more step-by-step than just "hit DEL or ESC" or whatever

. Getting at the recovery partition is not as straightforward as it could be (to keep from starting it by mistake), and he could wind up with a nice fresh install and no data.
I'm not 100% sure about the above, since I've never done it, but I'd advise to check out the procedure carefully before just saying "Sure - go ahead".
