Boot problems - BCD Win 10

D

DMWillms

Hello everyone, thank you in advance for reading:


I have a Lenovo ThinkCentre which came with Win10 installed on an SSD, with a HDD for documents.


At some far removed time in the past, I started getting the following error:

Boot Configuration Data file doesn't contain valid information for an operating system​

File: /BCD​

Error Code: 0x0000098​


I found a solution that seemed to work:

boot to command prompt, run bootrec /fixmbr, bootrec /fixboot, and then bootrec /rebuildbcd​


When I would do that, the computer would reboot and/or start just fine. For a time. At least until Windows Update ran.

Then the BCD error would be thrown again.


Now that routine doesn't seem to work any longer.


After research, I found this page:

Advanced troubleshooting for Windows boot problems - Windows Client Management

I started working through the proposed steps.

I have tried the StartUp repair tool, with no change.


If I run scanos at the command prompt, there are 0 Windows installations found.

If I try to export and rebuild the BCD, I have no C:\boot directory to put the BCD in. I was tempted just to mdir this subdirectory and resume the procedure, but then I noticed something peculiar.


After looking a little more closely, I see that my SSD Windows disk is drive D: in the command prompt, but shows up as C: inside File Explorer in Windows. (D: has no \boot subdirectory either, just FYI). My documents HDD is drive C: in the command prompt, but shows as E: in File Explorer in Windows.


In DiskPart, I see this:

Volume 1 C DavesDocs NTFS Partition 711 GB Healthy

Volume 2 D Windows NTFS Partition 237 GB Healthy

Volume 3 WinRE_DRV NTFS Partition 1000 MB Healthy

Volume 4 SYSTEM FAT32 Partition 260 MB Healthy Hidden



I am wary of continuing because the mismatch between the Windows drive (D: in command prompt, C: in Windows), and the fact that the documents drive is apparently addressed as C: during the boot procedure seems like a real good reason that the OS cannot be found.


Can anyone advise on my next steps towards resolving this?

Thanks.
