To my surprise, when I checked the boot order, I saw that the DVD drive was ALREADY first! Confused, I decided that if this wasn't working, I'd try disabling the hard disk altogether in the boot list. Upon a restart, I was simply prompted to insert boot media and press any key. After checking that the memtest CD was already in the drive, I pressed enter and got the same message. Repeated about 5 times with the same result. I just used Windows to burn the disk, and made sure that I chose "mastered" under formatting options, not the live file format. Did I do something wrong in terms of burning the disk?
