Is there a way to find out on which of the listed partitions is my linux distribution installed on?

I installed it with Wubi. Ubuntu is my distribution.

I'm aware of a similar question here, but it doesn't seem to provide a concise answer.

Are you on your Ubuntu partition right now running Ubuntu? (or some other linux distro?) And what release are you running? – Oyibo Jul 23 '12 at 9:26
Yes, I'm running it right now. I don't know which partition is it. Release; Linux ubuntu 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux – Tool Jul 23 '12 at 9:28
enter link description hereHello there, I am new to Ubuntu. I am attaching my Ubuntu Storage Device and GParted snapshot with this post. My question here is, where would be our data files (var/www/ ... ), in which Partition (/dev/sda1/ or /dev/sda6/). What is /dev/sda5/ linux-swap. Where to see other partition? – user162669 May 29 '13 at 5:51

In a terminal, run the command df and look at the output. The column headed "Mounted On" will have a "/" against the partition that holds your root filesystem. This is where your system is installed.

It appears to be installed on /dev/loop0. I have a follow up question though. If I want to install GRUB (lets assume I don't have it), would grub-install /dev/loop0 work? Since loop0 is a virtual partition, not a physical one. – Tool Jul 23 '12 at 9:51
I haven't installed linux on a loop device myself. It is my understanding that it loop0 is actually a filesystem within a file. I am afraid I don't know how grub works in this situation, sorry. Here's some info on loop devices in wikipedia – Jazz Jul 23 '12 at 12:19
Since this is a WUBI install, you just see the loop device, which is a file on one of those Windows partitions. IIRC, you instead need to look where /host is mounted. – psusi Jul 23 '12 at 13:18

Ok so if you're running Ubuntu 12.04 you should have GParted (a partitioning tool) installed, to find it click on the Ubuntu launcher icon and type GParted and it should show up like this:

Click on it and then you should get something like this:

Your Ubuntu partition will be on the one which has / in the mount point column. Windows usually takes primary partitions so Ubuntu is not likely to be /dev/sda1 or /dev/sda2, but feel free to post a screenshot of what your GParted shows if you need more help. Ubuntu is usually installed on ext File Systems as shown as an example in my screenshot above.

I actually don't have any rows with '/' as their mount point in gparted. But, using df I found out that my Ubuntu is installed on /dev/loop0 and gparted doesn't appear to show that. – Tool Jul 23 '12 at 9:48
ah yeah I misunderstood your question, didn't read properly that you were using Wubi, the other answer is far better in this case :) – Oyibo Jul 23 '12 at 10:45
