When a source disk contains one or more operating systems and all of them are convertible, the
boot mode can be automatically changed. Depending on the current boot mode, the target disk
may be initialized either to GPT or to MBR partitioning style.
If at least one operating system on a source disk is non-convertible (or the source disk contains
any boot volumes of the non-convertible OSes), the boot mode cannot be changed automatically
and the software will initialize the target disk as the source one. To boot up the target machine,
you have to turn on/off the UEFI mode in BIOS manually. Otherwise, the system will not boot
after recovery.
The following table summarizes all cases of recovering disks of a BIOS-based system to UEFI-based
and vice versa.
The plus (+) sign on a green background means that the source disk will be recovered without
any limitations.
The plus (+) sign on a yellow background means that the source disk will be recovered with some
limitations. To overcome such limitations, you might need to perform some additional steps.
The plus/minus (+/-) signs on a red background means the disk will be recovered, but some
issues might occur.
