I installed ubuntu 9.1 today, my friend also installed it using a disc which I borrowed
Everything seemed to go fine. I used boot camp to make a partition after going through the installation process I found out that, that was a bad idea and i just made a ubuntu partition of 18gb. I was able to get rid of the bootcamp partition so now i Just have free disk space left out of that.

I wanted to switch back to my Mac to get to work on somethings after I had installed ubuntu. However a after the GRUB and clicking on Mac
A black screen with words and numbers I haven't seen before popped up.
Here is some of what it said

panic (cpu 0 caller 0x2ad0d5): Incompatible boot args version 1 revision

Debugger called <panic>
Backtrace (cpu 0) frame return ad. 4 potential args on stack
** alota numbers here**


BSD process name corresponding to current thread: unknown

Mac os version: not yet set
**some other stuff here*

I really just want to use my mac again. It doesn't matter to me if I still have ubuntu or not. If someone could please help me resolve this in the easiest possible manner.
Thank you

can you boot with the option command (Alt) pressed during boot after the startup boing. It should give you an option to boot OSX.

Try booting from your Mac OS X install CD (hold 'C' during boot).

After you pick your language, click the Utilities menu and launch Startup Disk

Choose your OS X partition and reboot with your fingers crossed.

If that doesn't work, you can use your Ubuntu live CD to mount your OS X partition and copy any essential files to another disk (external, flash media, etc), and then use your OS X install CD to reformat and install OS X.

There may be a less destructive method to accomplish this task, but this is how I would handle a screwy hard drive.
