UEFI is a general framework for boot loaders based on a standard UEFI specification, which describes a standard environment and set of interfaces for platform firmware that allows operating systems to boot. The UEFI environment is a minimal boot OS upon which Windows devices are booted and the OS runs. Windows utilizes the Unified Extensible Firmware Interface (UEFI) to support the handoff of system control from the SoC firmware boot loader to the OS. If you read this: you will see that apparently it is standard for GPT formatted drives to have a 'Windows Boot Manager ( drive_name)' as your primary boot option, as it is now a UEFI boot, rather than a BiOS boot.Some information in this section may apply only to Windows 10 Mobile and certain processor architectures. UPDATE: Turns out it is due to the fact that when I reformatted my drive before the new windows install, I formatted it to GPT (UEFI boot) partition, instead MBR. If I set the option that does NOT say WBM before ADATA SX8200, I get the black screen that says 'Please insert boot media and hit any key' and it never finds the boot media.ĭid the install create a partition somewhere on the drive that caused this? And if so, how do I find out and/or can I format that partition without losing the ability to boot completely?

In BiOS, my PC will only boot with the following option:īoot Option 1: Windows Boot Manager (ADATA SX8200 SSD) Recently did a fresh install of Windows 10 圆4 on my ADATA SX8200 Pro NVMe M.2 and having a weird boot issue. This may be more windows related than gigabyte, but I'm asking here cause I'm on an X570 Aorus Master and am unfamiliar with the BiOS.
