I have burned 3 ubuntu live cd's and for some reason it won't boot on my macbook I have held down C and option keys even both at the same time but for some reason it won't boot. If it helps I have a core duo 2.0 macbook week 35 I believe

What are you using to burn the CDs? (Computer, burner, software...) What brand of media are you using?

[neverskatewsandles]

well I was using memorox but I now have the cd's that I ordered from ubuntu and my macbook keeps spitting out the cd's when I try to boot them.

[ghporter]

Does the machine play audio CDs? Can you get other CDs to do anything? Have you thought of cleaning your drive? If that's not what's happening, it sounds like a hardware problem.

[neverskatewsandles]

It play music cd's and dvd's fine i just tried it

[ghporter]

I'm stumped. It doesn't make sense that it would refuse a PRESSED CD but still play music CDs.

[neverskatewsandles]

I have no Ideas either any sugestions on what I should do?

[besson3c]

Does the disk mount while you are booted into OS X?

BTW, the plural of CD is "CDs", not "CD's".

[neverskatewsandles]

What do you mean does it mount?

[ghporter]

He means does it get added to Finder. Or does it do something else. What specifically happens when you put this disc into your computer?

[neverskatewsandles]

When I put in the CD I burned it does

[besson3c]

And what files do you see on the CD? When you get info on the CD, what format does it say it is in?

[neverskatewsandles]

I just see the ubuntu iso file and when i click on it all the folders ect. show up

So in the CD is the Ubuntu ISO file? If so, that is your problem.

You need to burn the *contents* of the ISO file, not the ISO file itself. To do this, from Disk Utility select "Burn Image" and then select your ISO file.

[neverskatewsandles]

Where do you click that at?

[neverskatewsandles]

this shows up when i click on the cd
Shot

And this shows up when I click on that

That's showing the contents of the .iso file. But you can't boot from that-you need to burn the .iso image to a disk that is bootable. Disk Utility should be able to do this for you (but I'm on a PC right now and can't give you the proper step-by-step process).

[besson3c]

never skate: Google "burn disk image OS X". I don't mean to sound like a prick or discourage you from experimenting with Linux, but this is the kind of thing you will need practice at researching yourself if you want to step into Linux. Moreover, I've already given you the instructions you need.

Here are the instructions again:

I'm feeling helpful today, so here we go.

In your Applications folder, there's another folder called Utilities. In there, there's an app called Disk Utility. With a blank CD in your Mac, click "Burn" and then select the ISO image you downloaded. Follow the directions, and you'll end up with a bootable disk.

[neverskatewsandles]

Ok I will try it hope this works. Please Excuse my ignorance here guys still learnin to use a mac a little bit

[neverskatewsandles]

got it to work using refit so thanks everyone for your help and I am posting using ubuntu now...

[black bear theory]

refit works well. but i just wanted to add my experience with linux livecd's on my mbp (before refit).

if i selected the disc to boot in the 'startup disk' pref pane some cd's would be spit out when booting and show a black screen. if i kept pushing the disc back in each time it was ejected, on about the third time, it would boot from it.

a similar thing would happen if i selected the 'option' key at startup.

the problem is convincing your computer that you really want to boot something other than macos x.
