autorun.inf takes care of autorun, which is a Windows feature that allows you to automatically launch a program from the cd once you inserted the CD in a player.
I think Choli means boot as in bootable cd, which is an OS independent feature that allows you to boot up your PC itself without use of any files or OS that already is installed on the PC.
A bootable cd is unfortunally not created with a file on the CD like autorun does. But it has special data written onto the CD itself.
Maybe UltraISO or MagicISO can help you out, although i'm not sure how they handle the exact position of the original files.
