Can't enable virtualization

Question

I'm trying to get my Android Emulator running faster, but i can't enable virtualization. When i open bios, it saids that it is enabled, but when i run Intel Processor Identification Utility, it display "Supporting advanced intel processor technologies: Intel(R) Virtualization Technology: no" . But when i look at the page about my processor on intels page, it saids that my processor supports virtualization

About my machine:

• Dell Studio 1749
• 4 GB Ram
• Intel Core i5-450M CPU (specifications)
• Windows 8 64bit

Thank you all!

Answer 1

I found the solution! In Windows 8 i need to disable Hyper-V.. I don't know why.

Answer 2

Hyper-V uses the VT resources and if they are already being used by another process then they will not be available for HAXM to use.
