Doom 3- corrupted autorun

[warlord_007a]

yeah... i burnt a copy of doom 3 from my friend. He is using a creative slix and as u noe, it has only a burner drive. as a result, he has to copy all the files to his desktop before he can burn for me. After that, i went home to install but when installation for disk 1 is copleted, i inserted disk 2 as told and pressed 'ok'. However, the same message 'please insert disk 2' appears. i read from several forums here and found out that the problem was due to a corrupted autorun. How can i fix this problem? pls hlp... anyone?
