Just a weeks ago I played this Team Fortress 2 with the hard drive of a friend that he connected in my PC :) then some weeks later I decided buying the game "orange box" when I tried to install the game it appeared a error message that says "Error 1327. Invalid Drive E:\"

HOW DO I FIX THAT?

Please help me...

For legit product, your best source of installation assistance is Steam Support (https://support.steampowered.com/).
