Ubuntu VM display not loading correctly on iMac 5k

[pmarq]

I'm trying to install Ubuntu (14.10 64bit) on my iMac 5k. After creating the VirtualBox VM [10GB, 2Gb mem], I load the Ubuntu ISO, and then the VM display is all over the place (see below). It seems Ubuntu is running, but the display isn't working correctly... I'm guessing is due to the iMac 5k resolution/controller. Any ideas what the problem might be?

The configuration of the VM is as follows: i (dot) stack (dot) imgur (dot) com/EUkMM.png

That looks like the screen one gets when installing any of the 15.04 .buntus. Not sure why you are getting it with 14.10.

None the less, once you get to that screen, hold the Host+F1 key combination, then the Host+F7 combination. Make sure you have the Function keys set to act as normal function keys on your Mac.

VirtualBox doesn't support Retina/HiDPI screens as yet so once you get Ubuntu installed you will have other issues. You will probably need to lower the screen resolution of your Mac.
