iMac G4 wont recognize lunux based disk's

[ChuckyZ28]

I have a iMac That I am trying to wipe the hard drive and install some flavor of ubuntu, however when I press the C key to boot from cd/dvd it does not recognize any of the linux based disks I have. I have tried DBAN, ubuntu 10.4, xubuntu 10.4, and kubuntu 10.4 all but strait ubuntu should work however none will boot. I tested one of the OSX install disks that came with the computer and it booted fine. Is there some step that I am missing or is this machine as big a piece of crap that I think it is.

System Specs:
Processor: 800 MHz PowerPC G4 (7450)
Graphics: nVidia GeForce 2 MX with 32MB of DDR SDRAM (15")
RAM: 256MB of PC133 SDRAM

Which Ubuntu or Linux CD did you use? PowerPCs need a different CD from the regular ones on Ubuntu's website. For Ubuntu, you can download the CD image from here: https://wiki.ubuntu.com/PowerPCDownloads.

Firt make sure you re using PPC ISOs not distros for X86 nor AMD

Second , many imacs are cranky when it comes to booting from burned disks. Always burn the CDs at the slowest speed possible.

Hope this helps

I wanted to Install Ubuntu but have no idea if the machine will support it, So im looking at kubuntu. I also tried to run DBAN=http://www.dban.org/
