Install OSX 10.5 .dmg file from External Drive

[mohicanspap]

I know that there are plenty of threads here that instruct me on how to do this but I have seen those threads and they jump around in a random order. Also its seems that those threads don't clarify what I exactly want to do here. I have a copy of 10.5 in both .cdr and .dmg files in an external harddrive and I would like to install either one of those into my PowerBook which is currently running 10.4 Now its seems that it is only possible to do this by making a partition either in the external drive or on the laptop. I really dont want to make a partition but instead to just replace/upgrade the laptop from 10.4 to 10.5 I really hope that I dont need the retail disc to do so. If there is someone out there that knows how to do this please comment or leave a response. I would really appreciate your time and effort for helping out a stressed college student.

:EDIT: This is not a torrent Leopard file but a backup i have made from the stone age of 10.5 and my retail dvd disc is long gone

There is no time for apostrophes.

EDIT: Then get a dual layer DVD? Or do you have the PowerBook 1.67GHz model without the DL-DVD writing capabilities?
Has a friend a Mac with a DL-DVD Superdrive or burner?

I do have a early 2009 MacBook with DL burning capabilities. How would I go about burning the image onto that DVD if you don't mind me asking?

Open Disk Utility, then choose Burn Image ...

Ahhhh. Well I will have to do this tomorrow and see where it takes me. Thank you for the help and I apologize for the misunderstanding in the first post. Again Thank You!!

Just had a thought. Would it work if I were to put the PowerBook in Target mode. Hooked it up to my MacBook Via USB and used Disk Utility to restore the OSX 10.5.dmg onto the PowerBook or would that just make a partition along with the 10.4 that is currently on the PowerBook?

That'd just make a partition of the disc, not install it. You need to burn it and install.

Okay I see. So the only way to just install it would be burning onto a DL DVD. Thank you for your comments
