I have the partition setup below. I have a dual boot set up where I initially installed windows on sda2 on a new drive. While installing, windows created the 142M (sda1) partition. Before the windows install sda1 and sda2 were the same, meaning I only had 6 partitions in all. After installing windows I installed Ubuntu 14.04.
My ubuntu install overwrote the Windows boot information. So now I don't get a windows option on boot. This is ok because I actually don't use the windows partition. In fact, I would like to format sda2 as a linux partition and use it for extra storage space.
My question: if I format sda2, will ubuntu fail to load? I don't know whether the initial windows boot information (which ubuntu later overrode) is on sda1 or sda2. Can I safely format sda2?
