How do I install Ubuntu 13.10 and dual boot Windows 8.1 pro? When I boot the installation USB I only get 2 options: "Erase disk and install Ubuntu 13.10", or "Something else". I tried "something else" but I don't know how to install it on a partition.

I reinstalled Windows 8 and it still didn't find it. I just then created the partions my self and it works! – DarthMaul Oct 22 '13 at 13:32
Congrats on getting it solved, can you add that as an answer? :) – carnendil Nov 14 '13 at 21:46

If you choose something else option it will directs you to select the partition in which you want to install ubuntu.And also force you to choose the linux-swap partition size.

Please allocate linux-swap partition size by following this link.

But some may require that. – Avinash Raj Mar 15 '14 at 20:04
@Braiam It's always best to start with a SWAP partition than have to make one later IMO. – Seth Mar 15 '14 at 20:08
@Braiam yes, you are correct.I edited my answer to follow the link for allocating swap size.You can setup a swap file easily, but think about a Ubuntu noob user.It's so hard for them. – Avinash Raj Mar 15 '14 at 20:13
@Braiam That's in your case. You must remember that you are a geek. Not everyone else is. Telling them they don't need SWAP and it's "easy" to get it later isn't a good idea in my opinion. – Seth Mar 16 '14 at 0:35
@Braiam Unless you want to hibernate. I know lots of people who do that on a regular basis. Or you have little RAM. I know lots of people that have little RAM. – Seth Mar 16 '14 at 2:47

Ubuntu 13.10 detected win8 but, i had to shrink win8 partition before: I think ubuntu only detects win8 when there's free space without partition.
