Can't follow install prompts

[pelouk]

Hello firenice03,

Thanks again for your input. I went into Bios but could not find a security tab. Could be because the HP link you provided referenced Windows 8 and I have 7 installed. Searched the site for a W7 equivalent but couldn't find one. I'm not sure if that might be because the computer shipped with Vista installed and I later replace that with W7.

Anyway, I'll have a mooch around and see if I can do with the BIOS.
