I have tried booting from ubuntu on my emac, but when i hold down the C key, or any other key like option. It just continues to boot up mac os 10.3, Panther. I really want to run ubuntu on my mac, instead of mac os panther.

My specs:

1Gb of ram 800mhz ppc g4 processor 40gb hdd Mac os 10.3, Panther.

Can the computer boot to any other CDs? Can you read the contents of the Ubuntu CD from within Mac OS X? – ændrük Mar 8 '11 at 20:04
Hi aendruk, it can boot from other cd's, it has booted from a mac os 10.1 install disk before.but the ubuntu one doens't even show up in mac os x. I know that it's not jut my eMac, because my ibook clamshell does the same. – user12034 Mar 9 '11 at 8:11
Do you think that it might not work because i am burning the iso to a cd using windows? If it is, how can I run Ubuntu on my eMac, because my eMac can't burn discs, it can only read them. would I maybe be able to use a flash drive? – user12034 Mar 9 '11 at 8:20
I had a similar issue with my eMac. Are you using a non-mac keyboard? – AndrewMC Mar 9 '11 at 16:29
Hi AndrewMC, I am using a 1999 apple usb keyboard (Two usb ports, power button,etc) I do also have a apple pro keyboard from around 2003. – user12034 Mar 11 '11 at 8:12

You should be able to boot off of this CD. My guess is that the CD did not burn correctly - try making another and check the ISO file to make sure the md5sum/sha1sum matches.

Make sure you can boot off your OS X CD if you still have one. This will ensure you can actually boot from CD (and didn't disable it somehow in openfirmware).

I burned my Ubuntu disk from an Ubuntu i386 system. A Windows machine should be ok.

Non-Apple keyboard should not matter. I do know that the boot is touchy and you may have to mash C (press & release it at different times) - holding it down on startup may not work.

If you only have a PC keyboard, the open-firmware shortcut is Alt+Super+O+F instead of Command+Option+O+F. Super is also known as the "Windows" key.

it doesn't read the Ubuntu CD right? try burning another – Broam Apr 14 '11 at 15:24

Hold down the Option key, then wait until the cursor turns into an arrow. You should see a CD with a penguin beside it. Click on it, then click the arrow to the right of it.
