Which version of Linux are you trying to install?
We need to know the answer. You have not bothered to reply. Please do so if you wish further help.

my prompt is showing root@(none):/#
The (none) means you have not named your PC. This is quite important for linux installations. No name = many things may be broken.
If fdisk -l
(Yes, it's a lower case "Ell", we have already established that) does not work, then things are seriously broken, and you need to start again, from the very beginning.
I suspect you have not installed your linux distro properly.
Linux isn't "windows", you cannot just click [OK], [OK], "I agree to everything, even though I have not read it, and do not understand it anyway", [OK], [Yes] and expect it to work.
Welcome to a new, and ultimately, better world. But
linux expects you to answer the questions posed, you can't just press <Return> and expect everything to work.
When you install any recent version of linux you should be asked some (fairly simple) questions.
If you do not know how to answer the questions asked of you at install time, don't just press <Return>, but ask
(here) if you cannot be bothered to work out (or search for) what your reply should be. Better still, ask (here) after
you have consulted the internet's various search engines.
Please don't have a "hissy fit" now, because I am trying to help you help yourself. We'll go one-step-at-a-time. We are here to help you if you can help yourself by providing us with some pertinant information as to your exact situation
