problem booting Fedora
i'm completely new to linux, my computer teacher has been urging me to try it out, so i got some old machines and put together a decent box. i know for a fact the harddrive, ram and cd-rom are good. i keep getting the error "please insert proper boot media, press any key when ready". the cdrom is showing up as the Sec. Slave and i cant get the harddrive to show up at all. HELPP please.
