This might seem a really stupid question. I have windows 8 on my laptop. I am trying to install Ubuntu 12.04 alongside it. My hard drive is supposed to have 20 GB unallocated space on it to install Ubuntu. Now I am in the installation phase. And I can't seem to find it.
There is a window which says installation type. There are options like
/dev/sda3 etc. But I can't seem to understand which one to select.
