I have been trying to install the Kali Linux 64 bit mini ISO from the official Kali downloads page recently. The way I was doing it was downloading the mini ISO and booting it up with Virtual Box on my OSx machine.
I tried three different times to install it, each time it would just freeze up whilst it was setting up Samba.
The fix I went for, which admittedly is a bit of a cop out but *did* work was to instead download the full ISO,Kali Linux 64 bit ISO. I am not sure if it was the fact it is a point release higher (1.0.8 instead of 1.0.7), or the fact there is clearly more stuff in the full image.
