Can I make VB2.4 install as MBR/Legacy instead of GPT/UEFI?

[Properjob]

The VB2.4 bootable USB doesn't offer any choices about setup, so it cleans the disk and makes it into a GPT format.

That means I can't clone the partitions and make the dual boot setup I initially envisaged.

IS there a way of forcing the bootable USB to use MBR/Legacy during its setup? Or perhaps a way of converting it afterwards to MBR and still be bootable?

If the system you install first is Windows or Linux why not install virtualbox or vmware and put virtualbox inside the virtualbox or vmware.

I got both the dual-boot Vortexbox software (runs quietly & efficiently as server software) and the W10 backup +VM version of Vortexbox working in the end. Neither Hyper-V nor VMWare were plug&play - which I'm sure were solvable problems given enough googling- but Virtualbox ran the Vortexbox 2.5 OVF version like a charm.

The 2012 vintage laptop only has 6GB RAM so running both W10 & a VM that uses 2GB is pushing it a bit & the fan comes on a fair bit as swap files kick in. It runs quietly & with loads of overhead (seen on PHPSysInfo) when booted into Linux running the VB2.5 software.
