    Default Live CD Wont Boot, Graphics Issue?

    Hey everyone I have a burnt live cd of backtrack 2 that I used on my other laptop and booted fine everytime. Gave me a menu I chose the first option, (kde). I just picked up a new HP Pavillion 6714 and I popped in my disc all excited, got to that boot menu and chose the same thing. After watching a console load all the usual stuff after a minute or two, I get a black screen with the 'X' mouse pointer, then it changes to the arrow, then the screen flashes black with some diagonal lines and it starts back at the 'X' and repeats over and over. I had a problem booting ubuntu from a disc until I boot into 'safe graphics mode' then it boot just fine, and after I installed it it ran fine, but said there was no driver for my video card. So im figuring it may be my video card, or a driver issue? Maybe its trying to auto choose a graphics setting but cant seem to find one?

    Anyone have this happen before? Any suggestions? Ive already tried the other boot options and none of the graphical ones work. And note that it is a good burn, I use the same disc on another laptop

    When do I type it in though? Like at the boot selector menu, or once the console is flying by or what?

    Boot codes or Cheat codes are parameters you can add during boot to syslinux to alter the behavior of Backtrack. Boot codes must start with "bt" (e.g. bt nodhcp) at the boot prompt. Below you can find some of them.

    Hmm ok theres a little more id like to add, when i just try to do the normal kde boot i hear the disc drive spinning up but then it stops and the screen just goes pure black. I tapped my power off button and instantly the screen popped up and console commands started whizzing by. So its getting hung on something and by tapping my power button just once it some how gives it life :?

    After doing that and loading some more things i got the problem i told you before, when i hit tab to change the boot command and tack on bt acpi=off at the end the screen does a couple commands i think then just goes black....permanently, i tired my little tap trick and the power just shut off! What gives?

    I am also using an HP 6704 laptop and have the same problem.

    Tapping the power button would occasionally work, well would it would bring the screen back. But usually would hang at floppy drive, although I don't have a floppy. I also get the X, then arrow, then flashing white horizontal lines. This continues to cycle every few seconds.

    I finally got to the login screen after numerous attempts, using the "tap the power button, then the CD drive ejected the BT disk and laptop shutdown. I also tried the acpi=off cheat code, but it made no difference in my case. This seems to be related to HP comps.
