Welp, I did all this work... and now I am going to condense and consolidate it for you. Aren't I a nice guy?

How complicated is this you ask? Fairly. But, once you get it down... it shouldn't take you much time to do again. You will NEED some stuff ahead of time. Now, there is ways around some of this... but, this is the tried and true method for me. So, if you don't like it... tough shit. 

Ingredients. 

1 Xbox

1 Desktop computer with 2 separate IDE channels. (Yes, IDE)

2 IDE cables

Torx drivers (15, 10, 16, 20)

1 CD Burner
Blank CDs
WinRAR

1 >=40GB IDE 3.5 Hard Drive (Trust me)

xboxhdm v1.9

NDure 3.1

MS Dash 5960

Filezilla

Ethernet Cable or Crossover Cable

Lots of time

Okay, so... go get all this stuff. The Desktop needs to have the ability to boot into Windows to burn ISOs on it. 

I will wait. Come back when you are ready.
