Won't read from a disc

[qanda]This thread is about the LG GH22L. Click here to see full specs[/qanda]I just finished putting my system together and am unable to install an OS.
The system will power up and I am able to get into the bios. It will not read a disc from the drives. It recognizes all of the parts as I can see them in the bios, yet it goes straight to the C: when I exit from the setup.
My components are:

Asus M3N78 PRO
AMD AM2 6000
2 GB PC2 5300 RAM
LG GH22 Super Multi DVD RW

Any suggestions?

I think you have to change the bootorder in bios first CD-ROM and then HDD

Okay, I forgot to mention that I have changed the boot sequence and tried it with both optical drives first. I’ve put in other discs as well. It produced the same results. I put the disc in my old machine and it read them fine.
