You have been somewhat misinformed as Xbox game discs cannot be read in a normal PC Drive. Read the link in my signature. Alcohol can only burn them to disc, after you have modded your xbox: Chip+Chip bios+Dashboard. And sent the xbox.iso (xbe) to your PC HDD via FTP. Its a fairly complicated process but once you've done it its easy.
As far as emulators go, look here:Xbox Emulators
