virtualbox.org

I bought Windows Server 2008 to go on my Lenovo ThinkCentre. It failed because I had 512MB of RAM, not 2048MB.
So I put the disk in my iMac (2.6GHz x 2 Intel Core Duo) to run on VirtualBox.
It goes through install before saying that I need a 64-bit 1.3GHz processor (screen shot attached).
It is already set to Windows 7 64-bit.

Thank you in advance for any help.

The Bios and the Processor must support VT.

Read the FAQ, its described whats needed for 64 bit guests.

I am running 10.6 with 64-bit VirtualBox.
I can run Debian 64-bit.
If you put the disk in a 32-bit computer it says "Failed to start".

Reinstalled VirtualBox, which fixed it.
