had a problem with my xbox HDD my wife was uninstalling a game and accidentally wiped the hard drive so I could not store any games on the HDD because it wouldn't let me in, and I could play any dvd films the only thing I could not do is play my back up games. So I looked around to see what could restore my hdd. I got "xbox installer evox 2.6" which it said was for mod chipped xbox only which was what I was looking for so I installed the evox 2.6 into my xbox. Now I can only play original disks. Everytime I put in a backup disk, I get a message "your xbox cannot recognise this disk, make sure that it is a xbox game, DVD movie or CD". It will not play DVD's without a DVD controller. When I try to get into the system info it says "warning this computer program is protected by copyright law". I cannot change anything. any disk that is not an original is not accepted. Can you please help

i have a mod chip xbox
