Oracle VM Virtual Box 5.2.20 r125813 (Qt5.6.2)
So… you’ve installed Oracle VM Virtual Box & you’re trying to install a
64 bit version of your selected OS.
However you have stumbled into a road block, you can’t find any 64 bit versions on the list.
Now I fixed this issue with the following steps:
- Go to into Programs and Features, on Windows 10 Pro Version 1809 (Build 17763.107);
- Then click on Turn Windows features on or off;
- Directly Under TFTP Client there is an option for Virtual Machine Platform, turn this OFF. It relates to Hyper-V and will kill any chance of getting what you want to do; and
- Make sure your UEFI/BIOS has Virtualization Enabled.
Once you have that done Reboot… Open Oracle VM Virtual Box and you should have your 64 bit options in the list.
