Windows 10: Windows 10 PC stuck in automatic repair/diagnosing you PC; rejects password

We had a power outage yesterday, and when I turned on my PC, I find I'm stuck in a diagnostic repair situation. My password that I know is correct is rejected as incorrect. None of the troubleshooting options in the startup menu are effective. I've tried removed the power cord several times and holding the button. I've been troubleshooting by Google and nothing works. Help.

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.

 

Laptop stuck on automatic repair and diagnosing pc.

Hi, when turning on my laptop it begins with automatic repair and then diagnosing pc, after this the blue screen shows up saying

"automatic repair couldn't repair your PC. press "advanced options to try other options to repair your PC or "shut down" to turn off your PC.

Logfile: C:/Windows/system32/Logfiles/srt/srttrail.txt"

If I go to open a command prompt in Advanced options > troubleshoot. it requires an administrator account which for some reason isn't on the PC?

I am unable to change or create an admin account as I have no access to the desktop so it continues to loop back to Automatic repair when clicking it.

I have put the windows version has windows 10 in the Windows version drop down box, but i haven't used it for a long while so it could still be on windows 8.1

 

Stuck in automatic repair /diagnosing PC reboot loop


Currently I am stuck in this automatic repair /diagnosing PC loop. I force shutdown my lenovo G480 laptop as it was unable to get out of sleep mode and this happened. Currently every option I am given results in the same loop happening over or it just doesn't work. I cannot afford to lose the data in my laptop as it is work related. What are my choices now?
