Mac osx won't start. stuck in windows

Hello all

My mac won't start it stuck at grey screen with the loading blinking circle. I tried to run fckdsk tried to boot it in safe mode but nothing happens. I took a picture of the screen when i tried to boot on safe mode but here it is:

It says Logfile is not clean. Will not be able to remount read-write. Boot in Windows.
And a lot of bug reports about launchd.

I have lost my Mac Osx dvd, what can i do to fix this?

regards

You don't say which version of OSX but the first thing to do is give Apple a call and get yourself a replacement OSX disc.

Sorry. It is Snow Leopard 10.6.8. I have Windows 7 installed with bootcamp.

Thanks for the reply, but I will call them if i can't find a solution online.
