now i have a recovery disk for microsoft windows vista 64 bit coming in the post. Hopefully tomorrow but because of the easter holiday it might not arrive til tuesday. What i want to know is is this the right disk (there was a choice of 2 for my computer. Windows vista or the one with the 64 bit thing) or did i need the one without the 64 bit thing?
We can't really tell you if the 64 bit version is the right one (the other one is 32 bit,) because that depends on what kind of CPU you have installed in your computer. You have to find this out somehow, perhaps by looking at the stickers (if existent) on your computer, or the manuals that were included with your PC.
also once the disk arrives is it as simple as sticking the disk in and letting it do its work?
I'm not sure about that. If there's no damaged hardware and the problem lies with the software installation, then the recovery disk should help repairing it.
