HI there,

I am connecting to the problem I presented with this post
viewtopic.php?f=1&t=80908

I have created a VM in an external device

Went to settings, and I changed
C:\users\user name\Virtual Box VMS (1)
in the folder of the external device
F:\Virtual Box

I created the VM with W7 64 bit

but

When I try to start this VM with oracle virtual box I got following error (please note that the system where the VM is running is a W7 64bit)

Hardware acceleration VT-x/AMD-V is enabled, but it is not working
64 bit guest won’t detect a 64bit CPU and therefore would not start.
Make sure of having enabled correctly VT-x/AMD-V in host computer BIOS.

Please could you help me in this issue ?

Please go thoroughly through the FAQ: I have a 64bit host, but can't install 64bit guests.
