Ok, well dumb question numero uno for today. But installing Ubuntu from the live cd I've got 3 options. Use free space on C: 29% of a 110G drive windows and previously installed programs and files are taking 71% I'm assuming that if i take this option it will not overwrite anything that's on there but instead install on the free space? What i'm worried about is will i be able to install programs and use the space that ubuntu doesn't really need from windows?
Option 2 is taking the whole drive which i'm not interested in doing.
Option 3 is manual, which i'm understanding most people do when setting up dual boots? When i click that one i get 2 partions opened up a 7G recovery and the 103 main partition. If i told it to take the 10G or whatever that most people have recommended does it just the free space on the partition or will it partition the whole thing?
Also i've got an external harddrive that it wants to install to when its plugged in during this phase, that's probably not such a good idea eh?
the tutorial i read on the ubuntu site said it will let you change the % do you have to type something to get it to work cuz i tried clicking everywhere and couldn't get into the box
