I have this original Xbox i never used for some time (something like 12 - 14 years). Lets just cut to the chase. It's missing a Hard Drive. It has a mod chip in it. I have 2 hard drives i am going to use either the 100GB or 500GB. What i get when i turn it on: I turn on the Xbox and i get an Error 16. I put the Hard Drive in and it gives me an Error 7. Why is it giving me this errors if it has a mod chip? How do i get the system working again? Do i need some recovery disc? Auto Installer? Give me something easy. I burned a program called Slayer EvoX on to a DVD-R. I put the disk on the Xbox and nothing. I still get the errors.
