well i just want to install OS 9 on a seperate partition that i've had sitting there for ages. it doesn't already have an OS on it, just a bunch of files, around 4GB worth. i just tried to install it before, but it said that it couldn't read some file on my HD, or something. then the install stopped, and i noticed the free space on that partition had just gone up? so i just wanted to ask... can i install OS 9 without erasing what's already on the partition? i was pretty sure you could, because i've done it before, but this time i did customize the install, i don't know if i could have clicked an option... i know i didn't have 'clean install' turned on either. just wanted to check that here, maybe someone can shed some light.
