Hey everyone i dont know if someone has asked this already or not.

I guess this is the right category to post this question.

I want to install linux on USB, which i can use in order to boot from Linux.

So the question is the following:
1. Can i do that?
2. Do u need any specific USB or any USB will be fine?
3. If I can do that, how can i do it?

Thanks in advance for any help.
