Used disc sanitizer now cannot load OS again
I have an HP Compaq 610 laptop. I ran disc sanitizer and am unable to reload OS system - Non-system disc or disc error. replace and strike any key when ready. I put the disc containing Microsoft Office Office Home and Student 2007 in the CD ROM drive but nothing happens. I also tried F10 - computer setup - "Restore Defaults" but didn't work. Please help!
