problem getting back to mac osx

[benbridle38]

Hi,

basicly i downloaded ubuntu, and burned the iso to a cd. i then booted with the cd in the drive on my macbook. Ubuntu ran, and i decided to click the run without any changes to your computer option.
This ran fine, however now i cant get back to my mac osx installed on the hard drive. When i turn on the computer without the ubuntu cd in the drive, it just comes up with something like "no bootable device--insert boot disk and press any key".

Really want to get back to osx as was only testing out ubuntu, and dont want to install it until ive partitioned off some space for it so i can dual boot off one drive.

Help would be most apreciated, thanks.

(ive tried booting off the leopard install cd)

It sounds like you used the Startup Disk Preference Pane to choose the Ubuntu CD to boot from. You should be able to hold alt/option on startup to choose to boot into OSX.
