[ubuntu-uk] Re : Re : Running From USB

[Pallottini Aymeric]

Your solution seems a lot better than what I am doing as you have a full install that you can update easily. I was just worried about the ability to boot on different systems but you answered that. 

Just one more question regarding the last screen of the installer, how do you install grub. I guess you have to specify that you want it installed on the USB stick? Do you need any other specific options?

Cheers, 

Aymeric

There's two things to note here. The short answer is "yes".

However you don't "install" onto a USB stick using USB creator. So
when you use USB creator from an ISO image or CD to make a bootable
USB stick you're essentially coping the live environment into the USB
stick. Once done you then have a bootable USB stick you can install
_from_.

If you _install_ _onto_ a USB stick then you lose the ability to
install from there, because you're no longer running a live
environment on the USB stick, but a fully installed one, just as if
you'd installed on a hard disk in a computer. Albeit a very small hard
disk that is highly portable.

I created my 32GB USB stick by booting to Ubuntu off a CD. Then
installed to the USB stick and used the standard encryption option in
the installer.

It works if you use the installer and not USB disk creator.
