Hello. I just installed a matrix modchip, after flashing it, to my xbox. I now want to install a 120 gig harddrive. I have slayers evox installer downloaded. I put it on a memorex dvd+R (burning at 1x speed) Ive done a ton of reading, but seem to get more and more confused with all the different softwares/ chip choices Am I supposed to install this with the original hard drive in, then change out with the bigger one? When I have the original hd in, and put the dvd in the drive, it says it cannot reckognize the disk. Did I miss a step? Im going to go buy a different dvd brand, and see if that makes a difference, but I thought maybe someone could point me in the right direction. Thanks for any help.
