I just installed Virtual Box on my pc to setup a virtual machine. I installed following a youtube video and it seemed work fine at first, but then I restarted it and now it's giving me an error stating

a critical error has occured while running the virtual machine and the machine execution has been stopped

It's has also suggested that I come to this forum with the contents of my "vbox.log" file and attach my "vbox.png" file. So that's what I'm doing now. Attached are the log and png files.
I hope this info should be sufficient, if not I'll be glad to provide any other info if needed. Any help would be much appreciated. Thanks in advance.

Your log file did not make it, but I have a question. Are you sure you are installing a windows guest or is it really that you are installing OSX in Windows?

My apologies I'm installing it in windows
