I have a Revision A iMac G3, and I burned Mac OS9 from my Macbook. I try to put the disc in and boot from disk, while holding C and it tries to read it then starts back into OS 8.5 and says "This disk is unreadable by this Computer. Do you want to initialize the disk?
Name: untitled
Format: ProDOS OK

Any help here? It is a European copy, and I have a US iMac. Maybe that might be the issue

----------

And btw, I have tried many other copies of Mac OS (Mac OS 10.1 10.2, 10.3) and all say the same thing.

Just asking... are you cloning an actual copy of the disc or are you burning an .iso? And what method did you use to burn the disk?

It was a .TOAST file, I burned it using the disk utility in 10.5

Now I am coming to believe I have a dead CD-ROM drive. Might have to replace.
And it was not a legitimate copy, I had to download it from the internet. I have tried every CD that I own in the machine and none work, even music CDs

Depending on where you are you might utilize the want section of Craigslist.
