My computer started giving me this message out of no where. "Verifying DMI Pool Data ... Disk Boot Failure, Insert System Disk and Press Enter". It is or was running on Windows XP. It was fine one day and the next it just gave me this message. Restarting it did nothing. When I press enter it just tells me "Disk boot Failure, Insert Disk and Press Enter". Aside from that it doesn't let me do anything. I can't run it in safe mode or do anything at all. I'm not sure if it might be a virus or if something else is affecting it. Any help is greatly appreciated.
