Can I make multiple separate profiles in skyrim? [duplicate]

Yes, you can have multiple profiles on the one system. As Ben has stated, simply select new game from the main menu, create your new character and once you have finished save the game. When you wish to save be sure to select new save because if you just select another save that is already present, it will overwrite your previous characters save game. Also try not to have too many save files for each character as it can get confusing trying to find a file if you have multiple characters on the go!
