I am at page 78 intel Visual Bios Reference dated January 2019.
Under Advanced>Boot>Boot Priority>UEFI Boot it states: "IF Enabled, BIOS will attempt to boot via UEFI before using the legacy boot sequence. UEFI must be enabled in orderto boot to a drive larger than 2 Tb.
If BOTH UEFI Boot and Legacy Boot are enabled, BIOS will attempt to boot via UEFI Before using the legacy boot sequence.
I have a USB-C connector Samsung T5 2Tb external USB SSD.
When it is formatted as NTFS and as a MBR type partition, I assume that to mean those are Legacy Boot indicators.
My Bios does not even detect this USB SSD when it is attched to my system in the Bios.
I have Boot USB Devices First enabled. IF enabled the BIOS will attempt to boot to supported USB devices before any other devices.
Under Boot Devices, USB is enabled.
Under Thunderbolt USB Boot, it is enabled.
I have followed the instructions here:
I have used the T5 on 2 different computers, my NUC8i7HVK and a Samsung Notebook 9 Pro and neither see the T5 in their BIOS.
I think the Legacy boot ability of this BIOS is either broken or non-existent.
If NTFS/MBR disks are considered Legacy boot devices why does the BIOS not see or boot from them?
also when I press F10 during boot, it does not show this T5 as a bootable device.
I have Legacy boot enabled in Devices. boot enabled.
Supposedly WintoUSB will create installable and Bootable External USB Drives, but I'm not willing to spend the money for it, only to find out this boot won't boot with it.
The NUC8i7HVK is UEFI based computer. Windows can only boot from GPT on UEFI-based computers running 64-bit versions of Windows 10. So, I think you need to convert your MBR partition to GPT type in order to boot in this computer. Please read more here: https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-setup-installing-using...
That is correct. The mention of Legacy in the BIOS Glossary is for previous generation NUCs. The HN/HV NUCs do not have Legacy support (i.e. no CSM). This is a thing of the past and completely unnecessary in this day and age.
In order to set up your drive for UEFI boot, you will need to delete all partitions on the drive and let Windows manage its partitions. Only by deleting all partitions will the MBR Partition Table be replaced with a GPT Partition Table.
Hope this helps,
You may use the MBT2GPT.exe tool to convert the MBR partition to GPT without deleting data on the drive https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt . There are also free utilities available (google "convert MBR to GPT).
