I've done it before but can't remember how. I have a partition on my laptop and Windows 7 is installed on the D drive. I've also dumped a load of photos on there as well as the C drive was getting full. (I guess I may need to get rid of them fro the D drive before reformatting right?) Anyway, I want to get the machine back to how it was when I bought it. Everything is backed up. I've looked around online (there are TONS of pages about it) but most of them talking about inserting the CD. Well I don't have one and don't need one as it's installed on the partition right? If you could either tell me how to do it or point me to a link that does, I'd be very grateful.
You say everything is backed up but did you also backup your photos on D? Because everything will most likely be deleted.
What you are looking at is a factory reset/restore - check your laptop's manual - it is supposed to start with a key press during startup (may also be showing which key when you start the PC).
