Every time i try to install Ubuntu there is no option for Windows 10 64 bit. Only 32 bit. 1 - do I have to have a USB drive to install? Can't I install to the VDI partition i just created? 2 - When trying to install using Windows 10 32 bit I get the following message: "This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot, please use a kernel appropriate for your CPU"

My system: Windows 10 Home version 10.0.14393 x64 based PC Processor - Intel Core i3-6100U CPU @ 2.30 GHz, 2304MHz, 2 cores, 4 logical processors Ram 6 GB

Any guidance is greatly appreciated.

  • Are you going to install Ubuntu in a virtual box in windows? Dec 4, 2016 at 7:15
  • The op states that his computer motherboard is x64 based that means that it is 64bit.. Dec 5, 2016 at 3:20

Your question is confusing.. But regardless, if you're trying to install a 64 bit operating system onto a 32 bit machine, it's not going to work. Either install an OS with a 32 bit kernel, or upgrade to a 64 bit CPU. If virtual box is only showing 32 bit operating systems make sure that your Host OS is 64 bits, Intel Virtualization Technology and VT-d are both enabled in the BIOS, and the Hyper-V platform is disabled in your Windows Feature list.


In order to run 64 bit guest OSes in VirtualBox, you must have a 64-bit capable processor with virtualization acceleration features. That's called VT-x for Intel or AMD-V for AMD. You can check your exact CPU model on the Intel or AMD spec sites to see. (Note it's OK to be running a 32-bit kernel, the processor just has to be capable.)

If the processor is capable and 64-bit OS types aren't shown, either the virtualization acceleration is disabled by a BIOS option -- go into BIOS setup to change it -- or some other virtualization package such as KVM is installed and has seized the virtualization hardware -- uninstall it.


Doing a little searching I see that Windows 10 Home version 10.0.14393 comes in 32bit and 64bit. if your processor is x64 based as you say, you should be able to install a 64bit Windows 10. If you are trying to install in VBox make sure that you have "Windows 10 (64-bit) checked.

If you want to overwrite Windows on your computer with Ubuntu 64bit, then using a Live USB for installing is considered the best option. Mkusb makes a fine Ubuntu USB installer.


I have 64bit windows 10 installed on my host system with an intel 64bit dual core processor. I cant find a 64bit Ubuntu ISO, only a 32bit ISO. I'll check to see that virtualization is on in the BIOS. But from what you have said my 64bit windows 10 host should be able to run a 32bit Ubuntu through vbox. Is that a correct statement. The error message baffles me as it says it needs a 64bit environment, which it has. so why that error message? And why am I not seeing the new VDI partition so I can select it as the install location? Sorry if these question seem elementary to you, but my last Linux install was a 32bit install on windows 7. it was much more straight forward. This install seems to have a mismatch between the actual hardware vs what the install software is identifying. Should I be installing a 64bit Ubuntu ISO? If so where do I find one?
