Live Cd For Mac

hi all,
i am in a sticky situation! my mac os x mini was working fine. i decided i would like to investigate ubuntu.
so i downloaded the ubuntu live cd iso and burned it onto a disk. next thing, i go to system preferences in mac os x and change the startup disk to be the ubuntu live cd. then i restarted my mac. the sytem booted straight into ubuntu via the live cd. so now i would like to get rid of ubuntu and stay with mac os x. i remove the ubuntu live cd and restart, hoping that it will boot directly back into mac os x.. but it does'nt.
now i have the predicament, where nothing else works on my mac except the ubuntu live cd! i tried all the usual apple cmd options.. tried to get at the open firmware.. tried to boot from the leopard disk.. all with no success. it does'nt recognise anything else.
also, when i do boot from the ubuntu live cd, the ubuntu welcome screen starts with a number of options, however i can not select any..
any Help greatly appreciated.
bien.

Linux Live Cd For Mac

Mac osx live dvd. Coreldraw for mac free download. Para los amantes de Apple, llego OS X live DVD. Esto va a permitir que mucha gente pueda probar un OS que esta muy bueno y es diferente de lo que acostumbran a usar. Por lo menos en mi caso fue con un live DVD como probe por primera vez Linux.
