Hello

I dont know how best to describe the problem but basically i get an error on Win7 Setup stating

Windows failed to start.........

File: \windows\system32\boot\winload.exe

Status: 0xc000035a

Info: Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.

Just after "Windows is loading files" screen

I do have the Intel Core 2 Duo E8400 CPU (So is 64-bit and Hardware Virtualised)

Im assuming a setting is wrong somewhere but can't see where???

Running Latest version of V-box 3.0.2r49928

Thanks in advance

Is hardware-V turned on in bios?

And don't forget the VM settings too. That need to match the requirements for 64 bit. Check the manual/VirtualBox FAQ for it.

Turned out to be small fault on my Motherboard

I use a gigabyte GA-P35-DS3R REV 1.0 and the Bios setting to enable VT-X had disappeared upgrading to the latest version F13 reenabled the setting and once done setting up a new VM (Windows 7 64) made it all work.
