2 SSD boot options in UEFI.

[and23]

Hi. Disk is SSD Samsung Evo 250GB with one partition.
Before format ( clean fresh Windows 10 on MBR partition) i had in UEFI only 1 boot option of my ssd : P1 SAMSUNG EVO 250 GB.
So after i format disk this time with GPT i install again fresh clean Windows 10. After finished installation it update to newest version of Windows ( from v10240 to newest ). And after this one more option in UEFI: SAMSUNG EVO 250 GB BOOT MANAGER and P1 SSD SAMSUNG EVO 250 GB.


So i guess its because Windows 10 upgraded to newest version and thats why SAMSUNG EVO 250 GB BOOT MANAGER was added?
Also i have on disk folder. Windows.old

Why would you format the SSD to be GPT? It is only 250GB.

Because GPT is a superior format regardless of the size of drive?

Because installing a modern OS under UEFI mode, causes it to register its bootloader with UEFI, so there's a bootloader entry, as well as a drive entry.

Who said this?
GPT = GUID Partition Table.
There is no reason to use GPT in OPs usage case.

Because it's more robust than MBR? There's no reason NOT to use it in OP's usage case.

Agree. Done.

GPT brings more to the table than just partition size limits. If you want to use the secure boot feature of Windows 8 and up then you need to use GPT. Also if you want to disable CSM (compatibility support module) in your UEFI for a faster boot you also need to use GPT.

OP - When you install Windows in UEFI/GPT mode this will show in UEFI as "Windows Boot Manager" but you will also still have an entry like you have which reads "Samsung 850 EVO 250GB". This is the boot override if you wish to launch your SSD in MBR mode however with secure boot on and CSM disabled trying to launch in this mode will likely just reboot back into UEFI.

Yes, I know, but he didn't say anything about those things, so, I wouldn't even bother using GPT for a small SSD.
For all we know, they could at some point use that SSD as a dual boot with an OS that don't support GPT.
