Currently, I'm using ubuntu 10.04 with 5 partitions (boot, root, home, swap, usr). I'm going to replace 10.04 by 12.04 whereas my hard drive has 80GB. Should I create multiple partitions for 12.04 or single partition? If multiple, then how many and how much for each of them?
Note: I have to use virtualBox on 12.04.
Would be very grateful. Thanks in advance.
