Problems installing developer preview in Virtual Box

I downloaded the 32bit version of the Developer Preview from here. I chose the 32bit version because I do not have the VTX AMD-v in my BIOS.

Then I setup a virtual partition in my vBox 4.1.2. Made the following settings

Enable IO APIC
Enable PAE/NX
Disable VT-x/AMD-V and Nested Paging

With all of that I tried to install but got bombed out (forgot to snip the messages but can try again to get them).

Does anybody have an idea where the problem could be? One suspicion I have is that I try to run the 32bit Win8 in a vBox on top of a 64bit Win7. But that is only a hunch.

Hi Wolfgang,
I don't think the 32bit on 64bit Windows can be the problem as that is my setup.

I have PAE/NX disabled and VT-x/AMD-V and Nested Paging enabled.

Thanks Keith. I will try that tomorrow. Right now I got it running in a Partition on another HDD and switch 7 and 8 with the BIOS boot sequence. But I like operating in vBox because switching between the OSes is so much easier.

PS: This was sent from Win8. I like it. Runs really well and up to here it was a breeze. Even the wife was amazed - there was no swearing at all.
