Well I've a pretty complicated hardware and software combination, so I am explaining the background first. I have a Macbook pro mid 2012 model with OSX Mountain Lion. I am dual booting it with Windows 7. Now I want to try out Windows 8, so that I can replace Windows 7 with Windows 8. So to try out I am using Oracle's VirtualBox to create a virtual PC and using Windows 8 trial (64 bit). All the three OS are 64 bit.
Now when I load the Win8 ISO (the ISO is in a usb drive), and boot from it in the virtual OS, there's some strange message coming from virtualbox which is
The virtual machine window is optimized to work in 32 bit color mode but the virtual display is currently set to 24 bit. Please open the display properties dialog of the guest OS and select a 32 bit color mode, if it's available, for best possible performance of the virtual video subsystem.
and then there's a windows 8 blue screen which says
Recovery Your PC needs to be repaired.
And then some
bootload.exe is missing.
I am adding the screenshot of the error too
Any idea on what's wrong here? or if I can do something about it?
