Also, try turning off Intel Hyper V and checking again.  That sometimes blocks it from showing a check box there.
I work with Vm regular. Now I buy new PC (Alienware Aurora R12). And... it doesn't support Intel VT-x [IMAGE] I think may be I am blind and read CPU specifications incorrectly. But if we open them [URL] We could see [IMAGE] It has VT-x technology. But I can't turn on it, because there is no any settings in BIOS, where I can do it. The BIOS version is last. I have all updates. [IMAGE] So I bought useless PC?
Aurora R12, Intel VT-x
