Can not reinstall Operating System?
Posted on 2011-03-05
Have a Dell Dimension E520 and need to reinstall OS. Don't have original CDs but have a good Vista and W7 CDs. Whatever OS Cd I use, everytime try to install from cd-rom, I get "Selected boot device not available - strike F1 to retry reboot, F2 for setup utility". I know CD-rom is good because I can boot into Bart UBCD. Any ideas?
