  1. " Operation System Not Found " ?? How to fix this problem?

    Basically i dont know wats going on but i was switching harddrives around to my computer to take some data off of it and when i put it back to the original computer :: it went to a black screen and says Operation System Failed

    and when i went into my bios it detected no dvd drive or harddrive.

    and i double checked the wireing and its perfect. but it keeps saying the same thing. i know the harddrive is not dead beacuse it reads on my other computer.

    i really need help this is my brothers computer and if i mess it up my moms gonna get pretty angry at me. any help would be apprecaite it thank you =D

    Do you know what master/slave mean when it comes to hard disks? Also, that it actually matters which plug goes where when you use a 80-wire IDE cable?

    You must have changed someting somewhere. Changed jumper positions, changed cable locations, changed BIOS settings.
