I just recently completed my first build. It booted up fine from both installer (used) hard drives. Then in the BIOS settings, I noticed it didn't recognize the DVD-RW/CD-R Combo drive I put in. After a quick flashback, I remembered I didn't plug the drive in. 
I promptly removed the case side and plugged in the drive. It went in fine, and the BIOS sees it. But it can't boot from a known good CD. HELP!
