Stop Win 10 from crashing upon updates

Hi guys, sorry if this was brought up before but I need help with my laptop.

Its a Lenovo Core i7 with 128gb SSD as the boot & Windows drive, and 1TB HDD for storage.

Every so often when Win10 updates, it will crash my laptop and would not boot. It stays at the black boot screen with the circling balls for some time b4 displaying boot error message. Windows repair can't fix it nor Automatic Repair, Safe Mode cannot be accessed. This happened to me 3 TIMES within the past year, the last 2 times I could still recover using SCANNOW & BCD repair trick, but this 3rd time that trick didn't work and I would have to reinstall Win10.

My question is, is there a way to prevent or preempt such crashes?

 

First step should be collecting info about the crashes to understand the source.

 

It says Boot Configuration Data is missing or error.
File: EFI\Microsoft\Boot\BCD
Error code: 0xc000000f

It keeps looping to this screen.

I hope this helps give a clue. Thanks.

 

Something happened either to EFI system partition or files on it.
Here is step by step instruction on how to re-create it (you can delete it before)

And here is BCD troubleshooting

This is what happens when y ou've previously used a bootloader to hack windows activation.

Thanks. Will try it out before reinstalling Win 10.

@Astyanax
Not understand. It can update just fine most of the times but some random times it will crash the bootloader. I had this same issue twice with my company work laptop (a Dell with Win10pro), once I repaired with the SCANNOW & BCD repair trick, and 2nd time it was successfully repaired via Automatic Repair. Hope this helps to clarify.

I am more interested to know how to prevent this from happening though. Thanks.

 

In that case you are experiencing a disk failure of sorts and the mbr/partition table is corrupting.

I tried to recreate the efi partition but got stuck at (create partition msr size=128) . It mentioned "No usable free extend could be found".

 

Then skip this step. Or create MSR of smaller size.

 

Ok, making MSR smaller (like 100) is still no go.
So I skip that.
I then tried to copy files of the EFI environment , but it says file not found.

 

Execute command to list the content in source EFI folder:

dir C:\Windows\Boot\EFI\*.*

- will it list files and folders?

 

It says "A device attached to the system is not functioning"

 

Which letters are for your partition with OS and EFI partition?

 

Right now OS is at C: and EFI became G:

 

So "dir c:\" will react with the same error?

 

yeah, same error. I see the volume in info column is stated as Hidden. Is this the cause?

 

Volume or partition?

 

All my volumes. When I "list volume" earlier to see the letters

 

Have you exited diskpart shell after you created the partition and volume for EFI ?

 

Yes I did
