Ubuntu on MAC Book

Yes.

You'll need to partition the drive first with Disk Utility if you want to dual boot.  You'll also need to install rEFIt to be able to boot from the Linux Partition.

Here is more information on how to do this:

OS X does not load , is it possible to install Ubuntu on boot up
(boot from disc/
usb)
?

Thanks

Please be a bit more specific with your question. Why doesn't OS X load? What version of OS X do you have? If it is 10.7 or newer, have you tried booting into the recovery partition by holding down Command-R and repairing the disk?

it is a Mac Book (early 2008) ,
OS may be = 10.5.2 or 10.6


?

Not sure why it won't load ,
sometimes I see : folder with question mark ,

sometimes : circle with slash ,


Tried : Command + S
= Nothing

Tried booting from OSX Disc , hold down Option - -
Nothing

Why do you want to boot from Ubuntu?
What are you trying to accomplish? Are you trying to erase and install Ubuntu, or trying to repair the Mac?
Do you have any of the original system DVDs that came with the Mac?
Do you have another Mac available?

Have original OS X Disc , v 10.6.3

Would like to repair MAC , ...


If can't repair - is it possible to install new OS?  Ubuntu?
Thanks


-No other MAC available ,

Is the OS X disk one that came with the computer to begin with, or is it an OEM disk from another Mac or a full commercial install disk?

Macs will not boot from an OEM disk that came with a different model Mac.

Macs will not boot from an commercial install disk that is older than the system which shipped with the Mac.

How can I get a disc that will work on this model MAC?

10.6.3 should work with that computer if it is a full retail copy and not an OEM disk. Full retail copies, I think, were black, OEM were grey. Can you tell if it is OEM or not?

Will it boot from the CD if you boot holding down the C key?

it is grey ,

not black

it boots from disc when holding down C , , then it says :
Preparing to Install

then goes to : MAC OS X can't be installed on this computer ,
-

Is this Retail?
NOT OEM , ,

Probably because it is an OEM disk.

?

The disk at the link is retail. My comment "Probably because it is an OEM disk." was in reference to your post "then goes to : MAC OS X can't be installed on this computer"

so retail OS X , should allow the install?
Thanks again ,

!

Thanks

Yes. You may have to run disk utility from the boot disk to repair the disk first.

You might see if the disk that you have gives you that option? Is there a menu item before it asks to install showing "utilities" or "disk utility" or "disk first aid"?

If so, then try to run "repair disk". If the disk can be repaired, you may not have to re-install the OS.
