In general, any supported operating system that can successfully be backed up by x360Recover can be virtualized, including both legacy MBR-BIOS based systems, and newer EFI-BIOS based systems.

One notable exception to the rule: XEN Server Virtual Machines with XEN-Tools drivers installed cannot be virtualized on x360Recover. XEN-Server 7.x+ paravirtual drivers are incompatible with the KVM Hypervisor used by x360Recover.
