I have a Lenovo ThinkCentre desktop computer. i bought it off a primary school, as they were mistakenly given one too many during their new shipment of computers. i have just tried installing vista (sad i know, but its the only thing better than xp that i have) and now whenever i boot the computer up, it says in the bios, after loading its startup thing, that the system has been tampered with, and then it asks me if i want to continue. it asks me to either press f1 or f2. f2 being continue, and f1 being setup. if i go into setup, it does not give me the option to save my changes and exit. It only allows me to exit without saving. How do i change this whitchcraft?
