I built a computer recently for the intent of gaming. Before I installed my CD drive, I checked the bios to see if anything was wrong. My hard drive showed up on the list and everything was fine. I then install my CD drive and it does not show up on the list, nor does the OS install. All I get is the error message, "Disk boot failure, insert system disk and press enter".
Please note that there was NEVER on this hard drive before, every single part is new and has not been used before.
Does it show up when the cd drive isn't installed? If it does, the RMA the board. If it doesn't, can you try hooking up the drive to a different computer and seeing if it shows up there? If it won't show up on a different computer, then RMA the HDD.
