Hello everyone,

Here is the situation,
I have recently installed Ubuntu on my laptop and today I made a bootable USB with Backtrack4 Final Press ISO so I could run it without full installation!

I am starting my laptop, then I pressing F12 to choose and boot from the USB and then this comes up..

EXT3-fs: sda1 couldnt mount because of unsupported optional features (240)
and at the end it writes...
(initramfs)_


I would be grateful if anyone could help me with this or provide any information.

V.
