I'm trying to run Kali live from a USB drive on a Dell Precision M6800 laptop. It has only worked once. I've tried it a number of times and most of the time it freezes once it is up and running or the mouse doesn't work or networking doesn't work. I've tried the USB drive on another computer and it works fine. I've tried another USB drive on the M6800 and I have the same problems. Any ideas would be appreciated.
