I experienced the same problem while trying to install a 64-bit version of Linux Mint inside VirtualBox. Disable “Memory integrity” in Windows 10.

Check if Windows 10 (host) is a 64-bit operating system.Make sure that “Intel Virtualization Technology” and “VT-d” are enabled.If VirtualBox has no 64-bit option on Windows 10, then you can try the solutions on this page to fix the problem. Note: This may be obvious for most of you, but your host operating system should be 64-bit to run 64-bit guest operating systems in VirtualBox. This tutorial will show you step by step what to do when VirtualBox is only showing 32-bit and no 64-bit versions of operating systems as options while creating a new virtual machine.
