I using lenovo thinkpad l421, to enable intel vt-x, I have to enter the bios first, Following this step:
- Restart the windows then Press F1 when Lenovo Logo appear in the first boot. When bios appear choice Config
- In Config menu, choice to CPU
- In CPU menu, you can enable Intel VT-x, just Enter Intel (R) Virtualization Technology, then choice Enabled
- Then hit F10, to save change then exit.
After this, you can running debian 8 with 64 bit system operation. Wish you luck
