Install Tiger using CD image

[Mario1776]

My Mac hardware doesn't seem to want to acknowledge that my burnt OS X install CDs are bootable.

I am trying to install OS X Tiger (10.4) on to my Power Mac G4. I am trying to use a set of burnt CDs created from images (.dmg) that I made a few years ago. I burned the images using UltraISO Premium 9.3.2 installed on my HP Laptop running Vista Home. I have had countless problems trying to get Mac hardware to read burnt OS install discs. After weeks of trying I managed to get Xubuntu Linux on to iBook Clamshell G3's by using a bootable flash drive.

I have tried using the key commands listed below to try to boot the 1st Tiger install CD, but none of them have provided any resolution.

C
Option
Option, Command, Shift and Delete
(Option, Command, o, and f) + (0 > boot cd)
(Option, Command, o, and f) + (0 > boot cdrom)

Is there a way to get the CD to be bootable? Is there any other way boot the Tiger install? Can it be done from a CD image stored on an external USB hard drive? If so, what format should the image be in (img/dmg/iso/other)? How should the drive be formatted (HFS/HFS+/FAT/FAT32/other)?

Thanks for any assistance you can provide.

The image should be a dmg or iso made directly from the original disc and burned to a fitting DVD-R or DVD+R medium (not DVD+/-RW). You can't boot directly from the image, though.

I'm not using an install DVD, I'm using a 4 disc set of CDs.

Same thing applies, though. Just replace "DVD+/-RW" with "CD-RW", i.e. use CD-Rs.

If the image was not made properly in the first place, then no amount of burning and re-burning will cause the CDs to be bootable.

How did you create the disk images?

Why did you use UltraISO Premium to burn them instead of using Disk Utility on the Mac?
