How big should partition be?

[MrSootentai]

I'm getting a 500GB hard drive soon and plan to partition it amongst Jaunty 32bit, Jaunty 64bit, and Windows 7 RC1 when it is released. For backup purposes I want to create a separate /home partition, but I have no idea how big the actual installs of the Jauntys (Jaunties?) should be.
Can anyone help me out?

Basic Idea:
Windows 7 RC 1 - ~100GB
/home partition - ~300GB

Would this setup work?

I had no idea how to search for this online because all I could find was HOW to create separate home partitions but it doesn't tell me how big the install partitions should be.

The set up should be fine. I have one desktop that runs two partitions with 34gb each. One partition has xp set up on it and the other has windows 7 RC, which is incidently very good. I also have a laptop a 500gb hard drive partitioned 250/250gb. That is running vista and windows 7.

I am installing ubuntu server on another desktop which is why i'm on this forum. This is my first foray into linux.

Just make sure you disable system restore in windows 7. Creating restore points can take a lot of space. I think the documentation mentioned installing windows first since windows likes to take up the entire thing, however you might wanna check that out since I do not really remember. I hope this helps. :)
