I'm trying to install Ubuntu 12.04 to run in VirtualBox alongside my Win7 64bit OS, without having to dual-boot.

I added the 64-bit Ubuntu iso to my VM, and powered it up so to proceed with the installation, but it prompted me with this error:

This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU.

Why does it give me this error, seeing as I have a 64bit processor? Is there a way that I can run Ubuntu via my VM in the first place?

When creating a VM using VirtualBox, the first screen you are presented with asks for the name of your new VM and attempts to auto-detect which operating system you're installing. Make sure that you select Ubuntu (64 bit) in the OS drop-down menu. Just selecting Ubuntu in that menu will result in the error you have described.
