To be more specific, i have a 16 GB USB with Ubuntu on it, and i use it to boot from it, but i want to save all my installations etc. so when i restart the computer or reboot again i wont have to restart my installations again. I also used terminal do install these programs, so will it be possible to sort of change the place where it is installed that way it will be on my C drive and ill only have to boot Ubuntu to run them. so in short I want to use the USB as another hard drive for the laptop. thanks,
Yes you can. But atleast you need 20 GB. So you can work freely. And your question is a duplicate of this post. Can I install Ubuntu to my 32 GB USB pen drive?
