The Windows 10 operating system was designed to install with the UEFI (Unified Extensible Firmware Interface) boot option and the resulting drive partition table GUID Partition Table (GPT). You may lose some support with the MBR partition table on WindowsВ 10, such as system acceleration with IntelВ® Optaneв„ў memory.

If you recently installed the operating system and the BIOS was set to CSM, setting the legacy boot option in the legacy boot media partition.

If you recently installed the operating system, setting the legacy boot option in the BIOS.

After upgrading to WindowsВ® 10 from an older operating system (OS) version, such as WindowsВ 7* or WindowsВ 8.1*.

You might have the legacy boot option set in the BIOS: If you are accelerating the system disk (OS Installed) proceed with details below.

Right Click on left panel for the Disk being checked (for example Disk 0, Disk 1, etc) > Properties > Volumes.

Open Disk Management by pressing Windows key + R > select Disk Management.

If the drive is a secondary/data drive (no OS installed), you can use third-party applications such as EaseUS*В to convert from MBR to GPT. If you have the legacy boot option set in the BIOS (Basic Input/Output System), it's possible the drive partition table is Master Boot Record (MBR). This article describes methods to convert SSDs from MBR (Master Boot Record) to GPT (GUID Partition Table) partition structure. We don't offer support for third-party tools.
