Stuck on this grey screen after booting up. This only happened after the update. So I did a fresh install, erased everything. Works fine with older versions of Kali, when I hadn't updated to new version I restarted it to see if I get the same problem, but I don't. Only on the latest version this happens. Then I do the update, everything works fine update completes. Shut it down then try to power it back on. As it's just about to go into the GUI interface just a grey screen. Don't know what to do, I've tried a lot of things and still doesn't work. Thanks.
