I was wandering if that's even possible! The other day my hdd crashed and it got me into thinking what if I could install a full OS on a usb(not live os though) from my cd/dvd that I had. So i fired up my pc without a hdd and with a kali-i386 cd along with my 4gb usb drive. Sadly the installation halted at the installation step which I assume is because of the 4gb size(it's not enough ig). Apparently I dont have any plans on buying a new usb drive for now. So..is that possible!!! And have anyone actually tried it though!


1) You should really get a larger size USB drive for what you are trying to do. I recommend something above 32gb, as 16gb wouldn't be enough. 2) To answer your question, as far as i know, the installer should use the flash drive as long as the internal drive is disconnected from the computer.

    Using the 'something else' option on the installer DVD, you can specify where to install, HD external or internal, USB or SD card if you want. You still need a drive that can hold it.
