its probably a simple solution. i rebuilt my entire computer. im using the same disk drives, hard drives etc as before, just changed motherboards ethernet and sound cards. when i start up the computer it says the "detecting IDE Drives..." it sits there for about 45 seconds then it says. Primary master, slave master etc... all say :none. it does not find them.then it goes on to say disk boot failure in another screen. i have gone into the system bios and tryed alot of diffrent things but cant seem to fix it. if anyone has a suggestion please help me out its hard to fix my computer when i need help but dont have a computer to use to get the help lol
