I'm having trouble getting OSx to work on Virtual Box.

I've got a dmg file I've tried loading and I have not had any luck. I'll admit straight off the bad that I have no idea what I'm doing... So any sort of feedback or help is greatly appreciated.

I tried installing the OS the first time and got the following errors:

I tried a second time under the option Server 64bit and anything fails to load.

Am I setting this up wrong (probably)? Do I need a different install of OSx?

My OS is Win7 64bit.
