![]() ![]() In my online research I found several forum posts recommended going into Settings->System->Acceleration, a tab that is greyed out for me. ( One in particular mentioned having to fix the BIOS.) The ones that were marked important, including the one that fixes BIOS, have been reinstalled.Īt this point I started looking into VirtualBox's settings. So I also investigated and uninstalled the Windows Updates from yesterday on, in case they were involved. (This is a work machine, so I am hesitant to load defaults without speaking to someone from IT first.)Īside from downloading and initiating an install for Visual Studio Express 2012 (which has since been uninstalled), little has happened on this machine since the Debian virtual machine was last working. ![]() The first two were enabled but the last was not. My BIOS has 3 options under Virtualization Support: Virtualization, Virtualization for Direct I/O, and Trusted Execution. When I searched this message online I found answers saying to make sure the BIOS had virtualization enabled. I chose to continue but as promised I made it as far as choosing between system modes (regular or recovery) before the screen blacked out. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. But when I tried it this morning I got an error message saying: VT-x/AMD-V hardware acceleration is not available on your system. My virtual machine of 64-bit Debian 7.5 (wheezy) was working in VirtualBox 4.3.12r93733 on a Windows 8.1 Pro (64-bit Operating System, 圆4-based processor: Intel(R) Xeon(R) CPU E5-1620 v2 3.70GHz 3.69 GHz) machine (Dell Precision T3610) yesterday. ![]()
