It's a problem with 4.3 I have same issue. In posts that I saw it suggested installi.g an older version.
This happened on a fresh windows install on my wifes computer, with Debian as guest.

I followed your advice and uninstalled the latest version
and installed the last version of Virtual Box 4.2

First difference I noticed is the that it detected the right architecture of my laptop
which the latest version didn't.

Unfortunately, I still see the same error.

Did you edit a registry key or enable/disable a setting in the VirtualBox image?

I haven't done it yet. But I have to go back & find the version of vb that was workin on my system before my reinstall. You also may have to remeber to remove everything.

I got it working eventually.

Downloaded Virtualbox version 4.3.12, installed it and got the error message that VT-x was not enable in BIOS
instead of previous E FAIL 0x80004500.

Enabled VT-X in BIOS, rebooted and launched Virtualbox and it started the Ubuntu 13.04 image.

So try the build I used above and enable VT-x
