Restore BIOS Based System Recovery Points to UEFI Based Computer
Want to restore BIOS based backup to UEFI computer? Follow this guide to learn how to make it step by step, no need to reinstall everything.
About UEFI and BIOS
Unified Extensible Firmware Interface (UEFI) mode and BIOS based Legacy mode are two different firmware that computers now use. By default, recent hardware boot using Unified Extensible Firmware Interface (UEFI) mode, which will prevent BIOS based system being installed.
Using UEFI mode, the system must be installed on a disk with GUID partition table (GPT) partition style, while in BIOS the master boot record (MBR) partition style is required. For those who want to restore system to another computer besides the original computer being backed up, these two boot modes must not be mixed.
Well, some UEFI based PCs has the ability to run Windows in legacy BIOS-compatibility mode, which makes it possible to restore BIOS based system recovery points to UEFI based computer.

4. Insert an installation disc or recovery drive to perform a bare metal system restore.
