In this guide, we will discuss the potential reasons along with the fixes to resolve the problem.
What causes VirtualBox won’t show 64-bit guest OS in Windows?
Spotting the exact reason the issue is occurring can be difficult, as there can be several reasons. However, we have listed some of the popular ones here:
- Virtualization Disabled – If Virtualization is disabled from the BIOS utility, the issue can occur.
- Hyper V – Hyper V is a hardware virtualization product that allows you to create a virtual machine. However, it could conflict with VirtualBox and hence the issue. It needs to be disabled.
- Core Isolation – Core Isolation protects against viruses and attacks by separating computer processes from your OS and device. However, this could cause problems in running a virtual machine. Therefore, it needs to be disabled.
- VM platforms – If you have another VM software on your PC, conflict could arise when using resources, causing the problem.
- Device Guard and Credential Guard– Apps like Device Guard provide hardware security and only let those apps run, defined in Windows code integrity policies. This can also cause problems.
