Problem booting BT3 Live CD

[Underclass Hero]

I set the "CD Drive" as my 1st boot device with the live CD, but nothing happened and I was booted into Vista which is on my hard disk.

I read the readme, but I don't have a DOS prompt installed, except for MS-DoS. How should I go about booting from the live CD now??

dont burn the iso file itself but the files that are inside the iso file..

Yeah, the md5 sum was wrong for that file
