installed kali2 dual boot with win7, everything went fine.. update to 2016.. pffff!!! my display was all blurry at the beggining, then reseted after 5 sec and worked fine. then i discovered my usual external usb wireless card won't work under monitor mode. in the evening iwconfig results my wlan0, but could not connect to wifi. dmesg and lsusb was ok. got angry and installed kali2 on wmvare. i hope for the best in the future of new rolling
