So I Am putting my G5 Back to work today, but I Need the lastest JAVA, but it seems 10.5 stopped at 1.5.0 java unless you have 64 bit intel, So I Want to install Ubuntu on it, I Burned the Ubuntu 10.04 PowerPC Alternate ISO and OSX Sees it fine, but when I Restart the Powermac it ejects the disk, and when I hold ALT and go in there it ejects the disk, and when I Put it in when its on the menu it just ejects it again. Is there a way to get around this? Its not a bad burn as it boots fine on my G3 iMac, but not my Powermac?
