From Legacy To Uefi Windows 10

On the latest motherboard (PC/Laptops) models, the manufacturers have added the support for the UEFI (Unified Extensible Firmware Interface), in addition to the traditional BIOS (Basic Input Output System) firmware interface. This is happened, considering the UEFI can back up hard disks with over 2TB storage disk space and offers better functioning, diagnostics and repairs of computers, even with no operating system installed.

UEFI is supported only on 64-bit Windows 7, 8/viii.1 or 10 Editions and since the Windows 10 version 1607 you cannot use the UEFI advantages (if your mainboard supports it), without having to reinstall Windows from scratch, because the UEFI uses the GUID Partition table (GPT), instead of the Legacy BIOS which uses the MBR Partition Table.

If you take a computer or laptop, with Windows x version 1703 (Build 10.0.15063) or subsequently, y'all can accept advantage of the UEFI without having to reinstall Windows, by using the MBR2GPT.EXE command line tool.

In this tutorial you 'll find detailed instructions to change the Legacy Boot to UEFI Kick, without having to reinstall the operating arrangement and with No Information loss. The instructions applies only if you have installed Windows 10 {version 1703 (Build x.0.15063)} on your computer.
