Ubuntu with Mac OSX Tiger

[Bob Salsburg]

Here's what I have:

MacOSX  10.4 server with System partition about 60 gb and a files 
partition about 60 gb. Both are Apple_HFS Mac OS Extended (Journaled)

Here's what I want to do:

Install Ubuntu 7.04 as dual boot with the Tiger server while keeping 
the almost 40 gb of files in place and possibly resize the system 
partition giving some space back to the files partition. I read 
somewhere that journaling would need to be turned off.

Will there be a 7.04 server release?

Please advise how I might best accomplish this task.

BTW. Each ISO I have downloaded has been reported by Didk Utility to be 
bad. Toast, however, happily opens them and makes the CD.
