Can I install Ubuntu on USB stick without touching Windows Hard Drive and boot from USB when needed?

I believe I read you must install 'Boot' stuff on computer main HDD!

It defies the need to have it on USB then.

I am no Ubuntu expert, I am mainly a Windows user!

Simply put yes you can. I keep a 16gb 'live usb' stick on my key chain for that very reason. The only problem that I have ran into is to boot from the USB you have to restart the computer and at some public places the is frowned on.

OK - thanks, I was actually trying one Stick and it was only 4Gb and 12.04 wanted at least 4.4Gb! My luck - I will get a larger one tomorrow. It is useful when you are somewhere else or repairing a computer. – mop May 20 '12 at 15:34

To run Ubuntu from a USB stick, the first thing you need to do is insert a USB stick with at least 2GB of free space into your PC.
