Ubuntu will not run on any version of vbox later than 4.2.16

[neemo69]

So for the last month or so I have been trying to figure out why I've been unable to run Ubuntu on virtualbox on my win7 host machine. Here is a video of the issue https://www.youtube.com/watch?v=aBVw...ature=youtu.be . After trying many older versions of virtualbox I finally found 4.2.16 to work. This problem does not matter which version of Ubuntu I've tried (12.04,14.02,14.04,15.04,and 15.10) both 32 and 64bit. I have an AMD FX6300 processor, ATI HD7750 video card, 8gb ram. Looking at some of the version change logs I cant really determine what changed that could cause this issue. Any help?

I note you have 8GB ram in the host and have allocated 5GB ram to guest.
That usually reports as an error as it is more than 50% of your host ram, though it does not stop the guest from booting when I try it on my system. Try reducing the guest ram and see if that solves the problem for you; I suspect it won't.

I have 8GB ram in my host Xubuntu 14.04 and have allocated 4GB to my guest of Ubuntu 16.04 as I did with previous versions of *ubuntu guest OSs, and I have never had a problem like this in any version of VBox, nor in the current VBox Version 5.0.14 r105127.

No, did not help. Even took it down to 2gb.
