Firstly LMDE does not delete all partitions. If you have XFCE installed then I assume that you simply told the installer to use the whole disk. I have attached a link to a tutorial which will explain all you need to know,http://community.linuxmint.com/tutorial/view/178
I would suggest that you create a swap partition and separate home partition.
Good Luck.
