Error booting from USB

[corrupter]

Hallo,

I've just setup an USB stick as described with Unetboot and BackTrack4 Final. However there is an error booting:
SQUASHFS error: Major/Minor mismatch, older Squashfs 3.1 filesystems are unsupported
and then BusyBox shell starts
the most strange thing is that the version of the squash filesystem on the usb stick is 4.0 and if I mount the iso in a virtual machine it works just fine. I can burn the iso but also want to understand the cause of this strange bahaviour.
The Usb stick is Kingston 4GB. Give some helpl please.

There could be any number of "things" that cause this. Best bet would be to start searching both here and google.

Well still don't have a solution but figured out that installation on the same memory stick works fine on other PCs' and still does not on mine. It must be my laptop Dell Vostro to be the problem but it's not too old to be incompatible(it's almost brand new). So any ideas??
