I have been having this problems for about a week now. It used to be okay after a few restarts, but today the solution doesn't seem to be working anymore. I have a GIGABYTE Z68MA-D2H-B3 mobo & I suspect it's the problem..
So basically when I turn on my pc, after bios will be the "Loading Operating System" with the black back ground. After awhile it will show "Boot from CD/DVD : DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER".
So I went into the bios, I discover that my mobo does detect both of my HDDs this time round(it used detect my 400GB barracuda even when it doesn't detect my 1GB WD boot drive)
EDIT: Bios vr. F10
