I was looking to do that, but its only got these recovery disks that came with the laptop. I'm assuming one has XP on it, but when you boot from them I cant see the recovery consol, just an option to format and reinstall. I'd rather not try that just yet!
I've had a similar problem before on my main computer (sys file corrupt/not found so couldnt boot) I was able to run scandisk somehow and that fixed it straight away...
