A year ago we explained how to use Kubuntu 8.10 from a USB device. Now, a year later, I was in the same situation, but with Kubuntu 9.10 instead. And since then we’ve made some steps.

Ubuntu itself brings an application to make a USB device boots Ubuntu. In the panel there is the application “K-> Applications -> System -> USB Startup Disk Creator” (o also with /usr/bin/usb-creator-kde command), which is very simple

We choose the ISO file, we choose the USB drive, and we click “Make a boot disk”. We wait a while and then we can boot from this pendrive.

But this only works for Ubuntu… What about the other distros? Well, there is the application unetbootin, which does the same with all linux distributions (wel, at least with a bunch of them).

Here we choose distribution, the ISO file, drive to write, and it handles everything.

Obviously, this ony works from linux. If you want to do the same from windows, you should ask for advise to our friends at pendrivelinux
