Windows 10 random automatic repair after changing boot priority.

Hello. So i have an Windows 10 Pro. Sometimes when i am changing in bios boot order from USB to HDD ( SDD ) windows starts booting with AUTOMATIC REPAIR and then restarting. Is this something with BIOS \ Windows 10 bug related? Tested on pc and on laptop , and sometimes it doing the same.


Situation on PC first,listen:

Few days ago after i change boot in UEFI BIOS from USB to SSD.
Then Windows 10 showed at 1 boot Automatic Repair.
When starting Windows 10 boot loader starts by "preparing automatic repair" and diagnosing pc.
Interesting is that if I restart Windows (after procedure mentioned earlier) it will boot normally. This startup problem was occured only when starting system again after shutdown or restarted pc from windows.So i was needed 2 boots to boot properly to windows.
But on pc, format was needed to remove completely issue and after format is fine.

Pc :
2x8gb Kingston Hyperx 1600mhz DDR3
SSD samsung Evo 250 gb
4790k stock
Asus Sabertooth Z97 Mark 2 with UEFI BIOS


Now laptop with old standard bios:
On laptop i made the same operation, change boot from USB to HDD and on first boot Windows 10 shows Automatic Repair. But it happened once and i cant reproduce. No format was needed.

laptop is very old with 2gb ram

Why on pc format was needed when on laptop not?



Thanks for suggestions.

Sabertooth 990fx won't boot to windows logo, it shuts down

to boot and enter bios and load windows, any todays PSU (with the correct plugs) will work, AFAIK

to enter BIOS only low wattage is used.
Then, during boot, the HDD and a bit later the videocard card start to demand juice, then the other devices and periphericals... so the total demand during boot up is incrementing step by step, that's why a failure halfway could indicate a PSU problem....
