Hi,

I'm trying to install Backtrack 5 (R3) on virutalbox, but every time I try to enter text mode it starts loading somethings and then eventually gives me this message:

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

Here are my system specs:
System
Model: Windows 7 RTM v2.0-x64
Processor pentium(R) Dual-Core CPU E5200 @ 2.50GHz 2.50GHz
Installed memory (RAM): 2,00 GB
system type: 64-bit Operating System.

I used these two backtrack os'ses to try to install it but i got the same message on both,
BT5R3-GNOME-64.iso
BT5R3-KDE-64.iso
(Don't know the difference between GNOME and KDE tho.)

If anyone could explain to me what i'm doing wrong or how to fix this it would be greatly appreciated.
