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.
