Apr 17, 2019 VirtualBox on Windows only supports one architecture x86, it does not matter if VirtualBox is a 32-bit or 64-bit process, the author's problem is connected to virtualization technology (VT-x) not being available to VirtualBox. The author indicated, in their question, they were running a 64-bit version of Windows 10. VirtualBox on Windows only supports one architecture x86, it does not matter if VirtualBox is a 32-bit or 64-bit process, the author's problem is connected to virtualization technology (VT-x) not being available to VirtualBox. The author indicated, in their question, they were running a 64-bit version of Windows 10. Problem: Why is Virtualbox only showing 32 bit? Solution: While I am installing Hadoop on my local system I found an issue that I am not able to install ubuntu 64bit OS while my host is 64bit Windows 10 operating system. Sep 16, 2021 I have downloaded and installed the newest VirtualBox 6.1 for my Windows 10 (64-bit OS), but when I want to install 64-bit Linux, the New-Create Virtual Machine only displays a 32-bit option, no 64-bit option.
I know this looks like same issue that's been reported numerous times over the years, but I think this one is different.
I've tried on 5 different 64-bit machines and made sure that on each of them both VT-x/VT-d are enabled and Hyper-V is not installed. Yet on three of the machines I am only allowed to select 32-bit guests and on the other two I can select 64-bit guests. What I've noticed is that the three machines that only offer 32-bit are running Windows 10 version 1709 and the two that offer 64-bit are running Windows 10 version 1703.
I know that Microsoft is pushing the 1709 updated so more and more machines will be running it over time. Can anyone else repro this issue? Any other workarounds I should try?
Thanks,
