After format is ok. No automatic repair. Even when i am changing USB to SDD is fine. But i am on GPT now.
I installed my Windows 10 in GPT partition. After this Windows 10 updated to new version and downloaded update.
In bios options i have SSD SAMSUNG and SSD SAMSUNG BOOT MANAGER. Why i have 2 boot of my ssd? What exactly it mean?
Likely one is suitable for legacy BIOS (MBR suitable boot) and the other is for UEFI boot (the one with BOOT MANAGER).
2 second question. So before format when i was booting from MBR partition had Automatic repair can you explain me why?
As stated before - because you were trying to boot an MBR disk as UEFI and there was no information to boot from where UEFI boot was looking, it then probably searched for alternate boot information or a Wndows Boot Manager to use, found it, and then booted on 2nd pass.
