Since I have an existing system w W7 (64 bit) on a PC I am unable to shrink the drive to accommodate the space needed for ubuntu. I can install another hdd or sdd and wonder how or if I can install a new drive soley for the ubuntu. Motherboard is a Gigabyte Z77X-UD3H 3D BIOS. I'm looking for the easiest way to do this without reinstalling or formatting the existing hdd. Any input greatly appreciated.
