Ripping a game using God2Iso Help Please

Hello everyone, i need help with ripping a game for my xbox 360. I have halo 4 original game disc and i want to rip that and turn it into an .ISO file. I use GOD2ISO program which converts all "Game on demand" files into ISO files and then i can put the iso files onto my hard drive and insert it into my XKEY which is a virtual drive loader or ODDE loader made for the xbox 360.

Can someone please help me to do that?
Basically what i have done is,
1. Insert the original game disc into my xbox 360.
2. Press the "X" button on my controller then click on "install game button". I choose to install on my 32gb usb stick.
3. Afterwards, i use USB xTAF on my windows 7 laptop to extract all those .DAT files that i have on usb drive and put them on my desktop in a folder named: "XBOX STUFF".
The files i extract are in the "data folder" not the cache. I choose to extract the "title file" which is a few kilobytes. Once i choose that file it automatically extracts the rest .dat files for me.
4. After extracting the files off my usb onto the folder on my desktop i click on "GOD2ISO". It launches and opens up.
5. I select my GAME ON DEMAND title file which is a few kilobytes and again it finds all .DAT files for me.
6. I i click on start process and afterwards i have a ISO disc image with a long name. If i load up xkey dvd menu, it will fail and ill see errors. I am unable to rip this game using this method described above. So please can you ansswere this question:


- Will installing game from original disc from my xbox 360 dvd drive onto a usb drive make an exact full copy of the disc or will it only install limited files?
If it is limited, then if i do not use A RGH or JTAG OR MODCHIP HACK, then would i need the disc in the xbox 360 dvd drive to execute the game using the xkey anyways or not?
If the iso file cannot be read by the xkey then how to launch it using the method above? I will post pictures if people ask. Just tell me. Im not sure if this is correct way of ripping games. I think that my games can be riped via the dvd drive attatched to my desktop but the tools needed for the CK3 probe lite and pro versions are too expensive and i think getting a desktop pc is too much work. I own a laptop and i need a method of ripping games without attatching a dvd drive taken from a xbox console into my pc. Actually i can boot win 7 via usb stick and attatch the xbox dvd drive via sata cable to my internat laptop hard drive bay and try that. Maybe it will work because if you connect the xbox dvd drive onto the desktop motherboard then the ck3 lite which costs $15 works fine.
I think that connecting the ck3 lite to my dvd rom for xbox 360 to my 2.5" hard drive sata slot will work. Or if it will not, and jungle flash will give errors, please can you people tell me now so i do not waste any money on these expensive and hard to use tools and equipment.

Thanks very much.
Bye.
Take care.
