Guys. I went to BIOS and loaded default settings , save and quit , i try to load to desktop and i get missing operating system. So i i put all 1 and 2 boot priorties on CDROM and 3rd boot priority on harddisk. Was having a problem booting from disk before missing operating system , thats why i loaded BIOS defaults so maybe i could boot from disk , now i dont have choice to boot from disk. CDROMs were working an hour ago , installed COD6 , the boot cd worked on my other computer , popped it in there and booted from the disk. I get now is DISK BOOT FAILURE , please put boot disk into system. I dont know why , please help me , my computer is an empy shell right now and a waste of 4000 dollars. Any one have any ideas on how i can reformat...? I dont know what to do
