You actually should just install ubuntu on two partitions,
swap. You can have ubuntu do this automatically by choosing to use the available free space (in other words, do not format your 60GB partition in vista before installing ubuntu).
Some will argue that you should use separate partitions for
/ and all kinds of things. This is useful in some situations, but for most common situations you are better off not doing this. Just let ubuntu choose for you and you'll be safe :)
You would often use a separate home in situations where you want to use:
- Multiple drives
- Multiple mutually exclusive ubuntu installs sharing the same data (could work with varying distros but not advisable to do this with different distros)
- Situations where your data needs to be safe in the case of a drive failure/upgrade (most normal installs are safe)
- The same drive is used by different systems.
NB: "Ubuntu's installer offers to preserve the contents of /home, so you don't need to be afraid to lose anything when doing re-installs or upgrades. – htorque"
On another note about swap - if you want to be sure that when doing large tasks you can have a lot of swap space, you can set your swap space to be twice the size of your ram, but either way, ubuntu will handle the requirements rather well if you choose to install on the blank 60GB partition.
