Windows 10 - Automatic Repair - boots in 2nd cycle

[and23]

Hello. My motherboard is Asus Sabertooth Z97 Mark 2 UEFI.
So i was had installed Windows 10 using MBR partition. During few days it worked fime.
But last time after memtest86 USB i change in my UEFI boot priority from :"UEFI USB KINGSTON" to "P1 SSD SAMSUNG EVO 250 GB" i am getting weird booting problem with Windows 10.

When starting Windows 10 boot loader starts by "preparing automatic repair" and diagnosing pc. Then after this i get screen with Your pc did not start correctly or Automatic Repair couldnt repair your pc . And when i click restart then Windows 10 boot fine. So i am needing 2 boots to boot properly to windows.

My disk is on MBR partirion. Is this related to my UEFI/Partitions?



Somebody said to me this:"UEFI booting requires a GPT disk. This is why Windows has to fix itself and only boots in 2nd cycle - as you keep trying to boot UEFI to an MBR disk."



Also i know that UEFI firmware can emulate BIOS functionality (CSM/Legacy) and work with MBR disks just fine. Or i am wrong? And cause is elsewhere?



I am a little confused. Thx for reply. My ssd Samsung Evo 250 GB , rams 2x8gb DDR3 Kingston Hyperx 1600mhz.

Changing boot options after an install (except for standard order) is generally not a good idea.

This statement is correct "UEFI booting requires a GPT disk."

So if you want that, I would suggest a re-install with the disk set up that way (UEFI). Or just move the order back to the way it was.
