Windows 10: BSOD and then automatically enter BIOS

When I'm using laptop and it's random BSOD then restart and enter BIOS EZ Flash Utility it's like this everyday. But I can get back into Windows by saving and exiting :

BSOD after updating bios. could not boot anymore or enter recovery environment

I now totally regret the decision of updating bios, following the suggestion of Lenovo Vantage. Since May the update of Windows 10 has significantly slowed down my slightly over 1 year old IdeaPad 730S. I thought the update of BIOS is likely the fix.

Well, I've entered the forever loop of BSOD with all kinds of error, when the update needed to restart. I tried to enter the Recovery Environment or even recover from a bootable USB with Window Installation Media, no success but continuing BSOD as well.

When the automatic repairing suggested the ESC, F1, F8 options, only ESC to the bios worked. All other lead to the same BSOD:

Trying the automatic repairing when restarting, the BSOD shows:

Recovery

Your PC/Device needs to be repaired.

The operating system couldn't be loaded because the system registry file is missing or contains errors.

File:\ WINDOWS\system32\config\system

Error code: 0xc0000017

The odd thing is that even with the installation media on USB, I still could not enter the recovery environment but the same BSOD.

I'd greatly appreciate if I can find a way to go back to the stage before the bios update, as I could not get into Windows at all. Or I can somehow fix those missing files through bootable USB?

Thanks!

 

bios

Hi all i am new in this forum, i need meanings step by step of each item listed in the bios Phoenix-Award

 

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
