I'm a newbie
and I'm trying to boot backtrack 3 in my laptop from bootable cd but got a black screen and a giant X in the middle of the screen.
I've tried every mode and got nothing.
but surprisingly it's work fine in my brother laptop.
So I figure out the problem isn't the CD, it will be my laptop.
My laptop graphic card is Nvidia GeForce GT 9600M
I tried to google it but got nothing as solution but now I do now that card is really bad in backtrack 3.

sorry for writing this here, apparently I can't post anywhere else.
don't know why!!
