Checking which partition Ubuntu is installed on

[Vincent_Siu]

Hey guys, So I've installed Ubuntu 12.04 alongside windows 8 on my labtop, and it just isn't working out, I can't use it at all, so I want to uninstall it and try a different version. Biggest problem though: how to find out which partition ubuntu is installed on? (I didn't use WUBI to install ubuntu, I used this method http://www.ubuntu.com/download/desktop/install-desktop-long-term-support)
I attached a picture of the disk manager (I know for sure that it's not OS or DATA or Recovery.) and the disk stuff

Your ubuntu install is on sda6 according to the df -h output. I think in the Windows disk management it is drive H:, though I have to admit a dislike of the way windows detects and describes partitions as it is a bit meaningless for Linux filesystems.

You probably also have a swap partition but I can not be sure about that, nor which partition it is, so the output of command sudo parted -l in terminal would also be useful.
