I have an hp pavilion a6450. I had to replace the hard drive (Seagate 500gb to Seagate 1tb). Now I'm trying to put the recovery disks on it but I only get a blank screen after I push F10. When I turn on the computer, I get the blue hp screen but F10 doesn't get me to any menus to help me set up my recovery disks. Help if you can. I appreciate it.
