If your Xbox DVD-ROM drive is, in fact, an OEM Xbox DVD-ROM, read on.
A) Try to boot from an original xbox game if you have one in good shape.
If that works,
try a KNOWN WORKING game backup disc.
If both "A" and "B" work, then C) re-burn your AID disc to the SAME brand of disc used in "B").
If "A" fails but "B" works, replace dvdrom AND/OR see "C"
If "A" works but "B" fails, and "C" fails, replace dvdrom drive.
If neither "A", nor "B" works try "C" anyway. If "C" fails, change DVDROM and then (if still no) change IDE cable and then (if still no) change HD. Change all at once or incrementally until problem is resolved.
If you do not have any of the above mentioned spare parts, you may not resolve your issue.
