After my sister's three months of vacation with no internet access, she got home and there were many updates for Windows 10 and Norton installed.
After reboot Windows didn't start. Instead "the boot configuration data is missing some required information" showed up.
I got a photo of it, but can't read the error code. It's something like
0x0000? The file is BCD though.
To solve this, her dude added her SSD disk in his own computer and according to them some sort of repair process finished successfully.
Then he put her SSD back in her laptop, after Windows automatic repair process it got stuck and Windows complains about
RecEnv.exe "memory could not be read" (
RecEnv.exe is Windows recovery environment).
Here is my diskpart list
Things I've done
I have created a Windows 10 32/64bits UEFI GPT formatted bootable USB so I can get to the command prompt
Memory tests through HPs utility have passed
CHKDSK /Rpassed; no bad sectors on all discs.
Sfc /scannowreaches verification 100% complete, but error:
Windows resource protection could not perform the requested operation
The requested system device cannot be found
- After this I tried to assign volume 4 the FAT32 disc letter
bcdboot bcdboot c:\windows /l sv-se /s N:error:
cannot copy boot files
bcdboot bcdboot c:\windows /l sv-se /s N: /F ALLBFSVC Error:
Failed to validate boot manager checksum (C:Windows\boot\EFI\bootmgfw.efi)!
Error code = 0xc1 Failure when attempting to copy boot files
So something is wrong with
bootmgfw.efi. How do I solve that?
I copied the
X:\windows\boot\efi to the same folder on the
C: partition and VOILA! then I was able to
bcdboot bcdboot c:\windows /l sv-se /s N: /F ALL
Next problem Windows can't start because of
ntosext.sys error code
0x000007b. Seems like the whole Windows has been messed up somehow.
