Unable to install 64bit guest on 64bit host

[tech330]

Hi All,

I have a host machine currently running win server 2008R2 . on which I have install VirtualBox 5.2.
When I'm trying to create a 64bit guest machine, the virtual box dropdown doesn't show any 64 bit machine option.
I checked and enable the virtualization in the Bios,is there anything else I need to check or disable to see the 64bit option in Virtual Box..

Currently I'm running "AMD A6-3620", I think which supports virtualization.

Thanks for all you're help.

Uh, WIndows 2008 has not been a "Windows Pre-Release" for quite some time. Moving this to "Windows Hosts".

As to your problem. FAQ: I have a 64bit host, but can't install 64bit guests.
