Re: USB On Xubuntu

Tried the RootDir approach & kept getting error reading cpu table 
messages.  Did find some instructions on the chroot (I think anyways) at 
http://www.webupd8.org/2014/01/how-to-fix-non-bootable-ubuntu-system.html

but no luck there as well.  seemed to work, but look like there was an 
issue with the cp portion & then when trying to launch update or upgrade 
it said something about using older sources.
