Installing multiple types of OS on one disk

[BreuerEditor]

I thought I've read this before but am unaware as to how to correctly do this:

I'd like to install Snow Leopard on my work computer, but want to install it on the hard drive as a separate entity so should I have trouble working with SL, I can easily go to the other OS (L) and work from there.

Does anyone know how to achieve this? If so, do I need to partition my hard drive to install SL?

Thanks in advance.

Partions are your friend. Just make sure to back everything up first.

Yes, you would have partition the drive - one partition for each OS.

Partition is the way. Use Disk Utility. Select your Hard Drive, click the partition tab, then under the volume scheme heading click on the + and another partition will appear. Now use the slider between the two partitions to designate the size for each partition and click apply.
