Hello guy, I have problem with Virtual Box. One month ago I install VirtualBox on my Laptop ( Windows 7 64bit) . I enable Inter Virtualization Technology and everything working good I can made a 32 and 64 bit system on virtual machine. Yesterday I clean my hard drive and I install Windows 8.1(64 bit too) on my laptop. Today I install Virtualbox and I can't make virtual systems with 64 bit. I don't know why, bios version is the same like on my Windows 7, VT-x enable. I try few times to reinstall virtualbox, chang some option in BIOS but it didn't change. Can someone help me? I have Lenovo Y580 with I7-36100QM.
