I'm new to linux and BackTrack but I'm quite good with Windows and BIOS settings.
Your new laptop could have a function that makes linux unable to boot. You may try
While you start your PC, press the F2 key (depends on your pc) to boot into your BIOS.
After booting in BIOS, look around and try to find I/O settings. You may try to LOCK or
TURN-OFF the 'New Card Interface'.
This worked for me, I'm now using linux with the settings I typed above.
I hope it will help you.
