I am currently on this screen:
after choosing "something else".
I have a 1 TB WD hard drive (
/dev/sdc) onto which I want to install it. I would like to allocate 100 GB of the 1 TB to Linux.
How can I do it without erasing the files already on the hard drive? Can someone give me detailed steps? Last time I tried this, I ended up erasing my whole computer. (I am running Windows 7 64-bit.)
