Well I was just wondering what partition belongs to which. On my computer I have Windows 7 and two Ubuntu systems (it was an accident, which is why I need to know which partition is which). So how do I know which one is which??

PS here's the codes:

jp@jp-Satellite-L555D:~$ sudo update-grub
[sudo] password for jp:

jp@jp-Satellite-L555D:~$ sudo fdisk -l

Partition table entries are not in disk order

Thanks to whoever can answer this. Another quick question, what is the extended partition??


If you have personal documents in at least one Ubuntu, or if you used a different username in your 2nd Ubuntu, then you can differentiate your 2 Ubuntu systems by looking inside the /home folder of each of them.


All that NTFS stuff is your Windows. Just let that be.

sda5 sda6 and sda7 are all logical partitions living in an extended partition.

The output of df -h ./ will tell you what partition you are currently on. So the other Linux partition (not swap) is your extra Ubuntu installation.
