Yeh, I did the Windows 7 one :) and I think I've got the latest BIOS update. There were a couple of other updates but said something about a USB mouse so I don't think it applies, or should I just try them all? There are 3 in total and the 1 I tried was already the one I have on my laptop. I think my next step is contacting HP...
Are there any real issues with running my computer with this Windows not genuine error message? Thanks.
