I got my motherboard and power supply replaced with a different board.. asus A7V8, so i have to reformat my hd, but i entered a bootdisk and it wont boot it goes to a:\ and then it wont let me type anything, i checked in my BIOS and it recognizes my hard drive and CDROM drive but when i goto Boot from CD beside it, it lists None and Disabled, so it says i dont have a cdrom drive in the bootup selection but when i check my Secondary Master it gives the name of my drive... When i put a cd in the drive to boot up it wont load the cd or anything, i hear it spinning by the time it gets to the boot menu, Someone please help im so close to getting my pc back
