Hello DiS computer boffins, I was wondering if you could help me out here.

So last night I installed the latest Vista update on my laptop and when I went to restart it it wouldn't start up!

I've tried starting it in safe mode and tried the HP recover disc I got with it, both didn't work.

This is my laptop: http://www.ebuyer.com/product/164845

Any help/suggestions would be massively appreciated.
