I couldn’t figure it out so I decided to poke around the administrator options in Windows to see what I could find. But since both were already enabled I was utterly flumoxed.ĭo I need to toggle the values? In other words, do I need to disable both options, save changes, reboot, and then enable them again? These were two key options that VirtualBox was expecting. Intel (R) Virtualization Technology was enabled and Intel (R) VT-d Feature was also enabled. In the Security Section, I noticed an option called Virtualization.įilled with a bracing hope, I tabbed over and hit enter but then noticed all relevant settings were already enabled! Thankfully, I remembered, the Hard Drive password and the Power-On Password, so after surmounting those obstacles, I removed those passwords and tried to see if there was anything I could enable to make VirtualBox display 64-bit Guest OS versions. That’s seriously the only way to get around that one resetting the CMOS won’t fix a forgotten Supervisor password. Thank God I didn’t enable a Supervisor Password or else I would have to replace the system board. As a side note, a few months ago I made another idiotic mistake: I enabled a bunch of BIOS passwords to make myself feel secure but then forgot how to disable them! Uninstalling and reinstalling VirtualBox made no observable difference so I booted into the BIOS to see what I could find there. This was super annoying because all my ISOs were 64-bit therefore I couldn’t use them until I fixed this problem. This post is going to be succinct and to the point.Įven though my Host OS is a 64-bit version of Windows 8.1, VirtualBox categorically refused to display any 64-bit guest OSes in the Create Virtual Machine dialog box. Today I want to save you the pain I encountered by showing you how to fix a problem I experienced in VirtualBox.

I installed Windows 8.1 from scratch using the Product Key, copied over all my software ( I probably should have used Ninite but I was too lazy) and then mindlessly enabled a bunch of options that I never enabled before.īut Alas! Stupidity has a cost and in my case it cost hours of discomfiting nights scouring Google for a solution. I experienced an extremely nettlesome problem after swapping out my traditional hard drive for a faster Solid State Drive ( SSD).
