Cannot install Windows 8.1 or Windows 10 as guest virtual machines

Reported by: spcmicro Owned by:
Component: other Version: VirtualBox 5.0.4
Keywords: Windows 8.1 10 AMD Athlon Cc:
Guest type: Windows Host type: Windows


I have a Windows 7 host system that is used for testing deployments of our application on numerous target OS's. These include XP x86 and x64, Vista x86 and x64, Win 7 x86 and x64. These all installed fine and are running. Win 8.1 and Win 10 will not install. I have tried multiple solutions on the web with no luck. I temporarily put another hard drive in the computer and verified that Win 8.1 and 10 will install properly. The processor is an AMD Athlon II X2 B26 which supports AMD-V as well as SSE2. It's supposed to support NX but there is no place in the BIOS to set this. The BIOS only allows virtualization to be enabled/disabled. Line 550 in the log may be a clue because it seems to be misidentifying the CPU: 00:00:02.449392 CPUM: Matched host CPU AMD 0x10/0x6/0x3 AMD_K10 with CPU DB entry 'AMD Phenom II X6 1100T' (AMD 0x10/0xa/0x0 AMD_K10) Line 663 reports that NX/XD cannot be turned on so maybe that's another clue: 00:00:15.067232 CPUM: WARNING! Can't turn on NX/XD when the host doesn't support it! I've attached the log file. Thanks in advance...

If you are talking about a 64-bit Windows 8.1 / Windows 10 then you need to set the guest OS type properly (Windows 8.1 / 64.bit or Windows 10 / 64.bit). You selected the 32-bit OS type.

And you need to enable NX on your Windows host. NX is currently disabled and cannot be enabled for the guest (which is requiring this) as long as NX is disabled on the host.
