Impossible to start BackTrack with new DELL Inspiron

[reallife]

Hello,

I've received today my DELL Inspiron 17R (Core i7 + Nvidia 525M) and I've tried to install BT5R1 64bits.
I launch Live CD, and at 16,47sec during kernel initialization, I've this message [Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS
Just after, system is Hanged, I've to disconnect power supply.

I don't know what does it means can anyone help me ?

Thanks

try it first on virtual box or virtual machine or check your cd, maybe there was a problem with burning process.
