Running Hyper-V on a Dell Latitude laptop

Re-installed my Dell Latitude E6500 laptop with Windows server 2008 R2, enabled Hyper-V Role and still … didn’t want t load a new machine or existing Hyper-V machine.
Just need to know that a “virtualization Trust Execution” settings needs to be disabled on the Bios (all the otehr Virtualization needs to be enabled.
Weird .. but works now !
