How do I upgrade a Bios if my laptop won’t bootup? During startup the system goes directly to this message “No OS found”. I want to be able to reinstall Windows Vista Home. I installed a new DVD Rom and Hard Drive but I still get the above mentioned message. I really don’t know what to try next except to upgrade the bios, but since I can’t bootup I don’t know what to do. Any help with this issue will be appreciated.
