Thanks for the replies, been really helpful.
Just awaiting delivery of the new hard drive
33coupe: Ive just installed a new hard drive ut still get the same boot error message.
Does the hard drive need need Windows loaded onto it before hand or something??
33coupe: Ah right, I wondered if that would be the case.
As I have no means of doing this I'm assuming I need to take it to a repair shop?
33coupe: Nice one, thanks for the links.
I think I might be able to get someone to download it to a CD / usb.
I'm not 100% sure which one I have tho. I believe it's 64bit, but the sticker says ' Windows 7 pro OA' .
33coupe: It's 4gb so yea def 64bit. Not sure which edition, I'm guessing home, but sticker says 'pro OA ' whatever that means
