This is my third failed attempt at dual booting windows 8.1 and Ubuntu (14.04 twice, and now 15.04). My computer is a Gigabyte Aorus X3 plus V3. When I tried to install Ubuntu using the 'something else' option (as it does not detect windows 8.1) it showed me that I had only 1Mb of free space, even though I had shrunk the windows partition by roughly 250Gb. I read on another ticket that this may be because of something that windows does to the free space with it's partition editor without warning. I extended my windows volume back to it's original size. What do I do now? How do I create space for Ubuntu without using windows partition editing tools?

  • Boot from Ubuntu install media.
  • Select Try Ubuntu without installing.
  • Open GParted (Partitioning tool).
  • Reduce the Windows partition.
  • Create a partition for Ubuntu (size that fits your needs).
  • Create a swap partition (size minimum matching RAM).
  • On the desktop click Install Ubuntu.
  • Choose Something else.
  • Select the partition you created for Ubuntu before.

    Swap size does not necessarily need to be as big as the installed RAM. One should decide that based on the installed RAM size *and* the expected system usage. Please read http://askubuntu.com/q/49109/367990 – Byte Commander Sep 25 '15 at 10:07
  • @ByteCommander : There are a lot of different opinions regarding the amount of swap space, such as about the reboot necessity topic. So as always, I keep recommending : Better stay on the safe side ! The disk capacity on modern hardware in most of the cases is large enough, so it really doesn't matter too much at all. Thank you for your hint anyway ! :) – cl-netbox Sep 25 '15 at 10:20
