virtualbox – Cannot use ubuntu core .img 22 for x64 machine

I want to install ubuntu-core-22-amd64.img. But I get on boot:

error: no such device ubuntu-boot.
i386 is not supported

My installation command for use on usb stick was:

sudo dd if=ubuntu-core-22-amd64.img of=/dev/sdc status=progress

I tried on my both Intel laptops.

Also my try to use in VirtualBox gives me the same result.. With use of command I created .vdi file:

VBoxManage convertdd ubuntu-core-20-amd64.img ~/VirtualBox\ VMs/ubuntu_core/ubuntu_core.vdi
