So I just burned a Ubuntu 12.04.1 powerpc .iso on a cd for my iMac G5 running Mac OS X 10.4.11 and it won't even recognize the cd. I burned it on my dad's Windows 7 laptop as the process is way easier (just 2 clicks).

Mac OS X 10.4.11 gives me an error when it starts and when the CD is in saying "the disk you inserted was not readable by this computer". What's funny is that I burned a Ubuntu Minimal .iso on a CD and it would totally read that and even boot it though it gave me some errors afterwards and I couldn't install.

I even tried going into openfirmware and hitting boot cd:,\tbxi but I get the error "Warning sector size mismatch can't OPEN cd:,\tbxi Can't open device or file"

Was there something wrong with the .iso I burned?

Mac OS X 10.4.11 won't even mount that .iso it tells me that the HFS file system is corrupt or something, but I know the .iso doesn't contain HFS file system.

Any help?

I downloaded the .iso from http://cdimage.ubuntu.com/releases/precise/release/ubuntu-12.04-desktop-powerpc.iso
