I have two hard drives. One is for Windows and the files I have accumulated over time. The other hard drive is an empty hard drive that I want to use to install and use Ubuntu on. I have the Ubuntu 12.04 ISO disc and I booted with that disc.
Should I convert the empty hard drive's file system to ext4? If so, how do I do that? Would choosing "Erase and use the entire disc" convert the filesystem to ext4 automatically?
