Try the command sudo fdisk -l. On my system it says:

Of course, yours may be different. Pay attention to the first and last column. The one that corresponds to System: Linux (/dev/sda2 in mine) is the one on which your linux OS is installed. Use your custom-partitioning tool carefully during reinstall - erase this partition and install ubuntu again on it.
