Virtual Box and 64 bit: Quick fix

By now it's also possible to install 64 bit systems within Virtual Box - as long as your computer is ready for that. But what if that's the case and you still don't see any option listed to create such a machine?

I can give you two things to check in order to solve that:

First: Go to BIOS/UEFI and check if the virtualization technology is activated. Easy, but often forgotten.

Second, check if no other Virtual Machine software is blocking Virtual Box - for example HyperV. If that's the case and you don't even need HyperV (which is included in Windows 10), remove it by going to Programs and Features.

A reboot is possibly necessary, but afterwards you can start Virtual Box, create a new VM and see also see 64 bit versions in your selection.
