If you're not seeing UEFI options in the BIOS setup, it's likely because your laptop uses the older BIOS firmware rather than UEFI. In such cases, you won't have the option to enable UEFI booting.
Why is my motherboard in legacy mode?
Most motherboards can set their BIOS (embedded firmware) to one of 2 modes - UEFI or CSM (Compatibility Support Mode). CSM is effectively a “legacy BIOS” mode, for use when there is something in the system which for some reason does not work with UEFI.
Is GPT UEFI or Legacy?
There is the Legacy mode (BIOS + MBR) and UEFI mode (UEFI + GPT). UEFI needs an EFI driver which only can be created on a GPT disk. Since GPT boots the system in a different way than MBR, if you use the traditional system installation method can cause a 'Cannot be installed to this disk' error.
Can Windows 10 run on UEFI?
Windows 10 utilizes the Unified Extensible Firmware Interface (UEFI) to support the handoff of system control from the SoC firmware boot loader to the OS. The UEFI environment is a minimal boot OS upon which devices are booted and the Windows 10 OS runs. For more information, see UEFI in Windows.
Does SSD use UEFI or Legacy?
UEFI (Unified Extensible Firmware Interface) mode and Legacy mode are two different ways of booting an operating system from an SSD drive. UEFI mode is a newer and more advanced firmware interface that replaces the legacy BIOS (Basic Input/Output System).
