wow really helpful guys, since I was only using my computer for 3 weeks I didn't expect the darn thing to up and die on me so fast! surely if I'm entitled to it I should be able to get it back on, not being computer lit, can I create one from my PC which has win 8.1 & use that when the unit comes back with a new HDD, I share all info on my laptop & PC so will be all the same stuff of does that just not work?
