[expert] Multiple Distros on One Harddrive

[Sevatio Octavio]

I would like to be able to 'try' a distro while not affecting my 
original.  For those of you that are running a system that has at least 
two Linuxes on one drive... What's your method for achieving this?  Also, 
what is the highest number of partitions you can have on one harddrive?
