I followed the guide from pendrivelinux and created a bootable USB stick with 8.10 on it. It booted fine, but then I tried to run updates and install some more apps and when I rebooted I got an error about busybox v1. something. then the prompt just said-

What's the best way to make a live persistant USB from windows? Shouldn't I be able to install updates without messing it up?
