Hello,
I have a HP DL370 G6 server running Windows Server r2008 R2 as a Hyper-V HOST that, after a reboot, will not boot anymore. We're getting Windows failed to start \Boot\BCD 0x000000f -- An error occured while attempting to read the boot configuration data. I have booted into the recovery console and tried the usual bootrec /fixboot, bootrec /fixmbr, bootrec /rebuildbcd. The first two commands "completed successfully" but /rebuildbcd gives:
Succcessfully scanned Windows installations.
Total identified Windows installations: 1
[1] C:\Windows
Add installation to boot list? Yes(Y)/No(N)/All(A):y
The requested system device cannot be found.
chkdsk says everything is good.
sfc /scannow says everything is good (after starting the "TrustedInstaller" service) - before starting the service I was trying sfc /scannow /offbootdir=c:\ /offwindir=c:\windows but getting the error "Windows Resource Protection could not perform the requested operation".
I also read somewhere when trying to use bcdedit that if the system is running x64, but the cmd is x86 (running from \Windows\SysWOW64). I tried "\Windows\sysnative" but no matter what, I get:
C:\Windows\System32>bcdedit /enum
The boot configuration data store could not be opened
The requested system device cannot be found
C:\Windows\System32>bcdedit
The boot configuration data store could not be opened
The requested system device cannot be found
Onnnnn to DISKPART now. When I issue the list vol command, I don't see any partitions LABELED WITHSystem or Boot, almost like my entire boot partition has disappeared! I'm used to seeing the System partition being very small (~500 MB), but all I have are my larger drives (C (operating system), D (partition for VM VHD's), E (DVD-ROM)).
I understand the Boot volume can be large -- on my Windows 10 computer I have C as my Boot volume (49 GB), but my System partition is only 549 MB, and under the "Info" column in DISKPART --> list vol it is reporting "System". I don't see System or Boot on my HP DL370G6 anywhere.
If I go into the HP "Boot Disk Test" it tells me:
Boot Disk Status: Pass - Disk Present
Boot Disk Ready: Pass - Disk Ready
Verify Boot sector: Fail - Valid OS Boot Sector Not Present
-------------------------------------------------------------------------------
If I boot from System Recovery, get all the way into "System Recovery Options" where it says:
"Select an operating system to repair and click Next. Note: This feature cannot repair operating systems earlier than Windows Vista.
There is NO OPERATING SYSTEM PRESENT. So, I tread through HP's websites to find my driver for the HP Smart Array P410i Controller, and found it. I loaded the drivers and when I saw my RAID controller, I was very very excited, thinking alas, when I click Add Drivers..., I will finally "see" my OS and this System Recovery tool can do its thing. My OS never shows up. :(
As you can imagine, I am at a loss and that is why I am here. Hopefully someone has run into this and knows of some kind of solution or recommendation.
Many thanks in advance!
