Difficult Upgrade to 10.5

[chopper]

I'm trying to upgrade my older Intel iMac to 10.5 from 10.4 so I can run Chrome.

The CD/DVD drive is junk on this unit.

I made a disc image of the 10.5 DVD and put it on the desktop, click install and the computer re-starts--but will not begin the install process. It just goes to the 10.4 install.

Hoping to just do an upgrade and not have to steamroll the 10.4 install.

Any tips on getting the install process to work?

TIA

do you have another Mac? use FireWire target disk mode

EDIT: you can do it both ways: boot the Mini in FWTDM (holt down T as it boots) and hook up to another Intel Mac with good optical drive and install from there, as the Mini were a simple external Hard Drive

Or you can put the 10.5 DVD in the other mac with good optical drive, boot that in FWTDM and hook up to the mini, and both HD and Optical drive should show up on the Mini. Eject the other HD so you don't mess with it, and use only the optical drive as if it were an external FW optical drive

clone the installer disk image to a hard drive.

I'm pretty sure it's coded not to run from a .dmg, hence the above suggestions.
I tried this with 10.6 and it was sophisticated to give a pretty little screen announcing that it had to be installed from an optical, but that funtion seems to be missing from your 10.5 updater.

when it reboots, the DMG on the desktop isn't recognized as a bootable disk image.

See if it'll run from a flash drive.

Not nearly as much trouble when my Mac specialist upgraded my 5+ year old Power PC Mac to 10.5.8

I am still wrestling with it!

If it is not broken, don't fix it!

Your installer needs to be run from a bootable drive. You can make a bootable installer on an external drive or on a flash drive by using the "restore" function in disk utility.

Here is a guide for making a usb flash drive installer here:

This guide is for Snow Leopard but the same process works for Leopard.

10.4 is kind of "broken" at this point, especially if you have an Intel mac.
I'd recommend going right to snow though-- a few things that are quasi-broken in Leopard work well in Snow Leopard (e.g. Preview.)

I'd vote for 10.6 instead as well, but can it be installed from a non-optical drive? (e.g. USB flash drive)
