Help Creating Bootable Mac OS 9 CD

Well, I’m stumped and have spent way too long and tossed way too many CD-Rs in attempt at this. All I want to do is get an OS9 disc bootable (shouldn’t be that hard, right)? I have a 12” PowerBook G4 I’m using as my burner device, running 10.4. For images, I’m using an OEM 9.2.1 install CD, with corresponding .cdr image created in disk utility, and also the universal 9.2.2 downloaded from MacOS9Lives.

I first tried burning directly in disk utility- no luck. Then I found out about toast, so I installed 5.2.3. I was able to select “bootable” there, thinking that would work, but nope. I have tried “write session” and “write cd” options, doesn’t make a difference. All my old laptops will read the burned discs just fine, they just won’t boot from them.

What am I missing? Surely it isn’t supposed to be this hard! Do I need a machine running OS 9 to actually burn the disc?

So, first and foremost, how are you making your 9.2.1 disc? It will only work as a startup disc if you make the entire disc into a .cdr. The difference is that you need to make an image of the entire device, not the volume itself. No matter how you burn the disc, if the entire device is not made into an image, it won't work. This is what you select, for example, to make an entire disc image (I just happened to have Fallout 3 in my Mac Pro drive):

Make sure to have the device highlighted as shown above, not the disc itself. Then, make a new .cdr. If you are already doing that, then I would have to think of something else. You can burn a correctly made image to disc normally in Disk Utility without any craziness: it should just work.

That might help with making an image - note you are possibly using the wrong options in toast if it offers you "bootable" as an option (weirdly)...


Once you have the image, burn the image using the Disc Image option in Toast, not disk or volume.

It genuinely seems to be. No software seems to make it simple, especially on the writing side. You always have to do exactly the right thing.

I did actually try that, but Disk Utility didn’t want to make an image from the device. However, if I select the volume itself, I’m able to create the image (See screenshots). Maybe I need a different version of Disk Utility?

If not, I would try "Session 1." Also, you can try the device as I suggested, but right click on it and some option to make an image should show up.

Well, here’s one way that works (as long as you have a good CD to start with). Using the copy command in Toast 5, I was able to make a bootable disc. Unfortunately I’m still unsuccessful at burning my own image or an image of a disc, but I guess that’s a problem for another time. One of these days I’ll get 9.2.2 on my titanium PowerBook. The amount of OS 9 bootable machines I have with a CD burner is very slim!

That's a different question :) I didn't realise you were asking that. This might help.


Sorry it is written for Linux, but the "making an image" bit is the same whatever platform.

Oh, but you need a version of the CD ROM driver extension in the system folder that supports the computer you're trying to boot, so don't use a Mac OS 7.5.5 installed extension with a G4.
