Boot camp no osx partition So some time ago i used boot camp to install Windows 8 pro.
Now i want to switch back to my mac/osx but there is no osx partition

Screenshot of boot camp on windows: (Ingore the langauge, it's in Danish)



I have searched around for an answer but i can't find one.

Thanks for reading

Note 1
I have tried ALT at the start-up of the computer but there is now OSX disc. Only a windows one. And i have tried to reinstall OSX on one of the discs, but i gives me a error (Can't remember the error, but i couldn't delete the disc either)
Try holding down the alt key while powering on your Mac. This should yield a boot device selection.

If this doesn’t help, try booting in Recovery Mode as outlined here: http://support.apple.com/en-us/HT4718
There you can run Disk Utility to check wether your partition is corrupted.
