New build - Can't boot from a dvd-rw


I've just finished assembling my brand new build and it seems that I can't boot from a dvd-rw.

My mobo is a Gigabyte GA-P35-DS3L and my dvd drive a Pioneer 212D Sata.

If I insert my WinXP CD, it is dectected and boots from it.
If I insert a dvd-rw with Ultimate Windows Boots disc on it, it doesn't boot from the dvd drive just like if I had inserted a non bootable disc.

I played a bit with the bios settings and I found that if I enable the AHCI thing I can finally boot from the dvd-rw. But I read that enabling that option can cause some troubles.

On my old rig, the dvd-rw boots fine with a Plextor P716a.

I need help on this, I'm not familiar with SATA dvd drive.

thanks for your help.

  1. Perhaps, the UWBD is corrupt? Try another one.
  2. Well it seems that the problem really comes from my UWBD cause I just tried with a Vista DVD and it can boot succesfully from it even with that AHCI option disabled.

    What's AHCI and should I enable it ?


    Gen-speak, you enable it for RAID before installing windows. After, you might get BSOD's in XP. Vista is ok.
