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).
