Howdy,

I am trying to recover my system and need to recreated boot files, boot sector and Boot Configuration Database.

Stage I. Adding boot code

1. I patched system partition with boot code:

bootsect /nt60 C: /force

This works fine and returns:

Target volumes will be update with BOOTMGR compatible bootcode.

C: (\\?\Volume{GUID})

Forced dismount complete, open handles to this volume are now invalid.

Successfully updated NTFS filesystem bootcode.

Bootcode was successfully updated on all targeted volumes.

The {GUID} returned here is the volume GUID for the volume with assigned C: letter. This same GUID can be obtained by using mountvol command.

However the problem is that system device cannot be located so that the following command:

bootsect /nt60 SYS /force

returns an error:

The system partition was not found: The requested system device cannot be found.

STAGE II. Adding boot data

bcdboot d:\windows /s :c /v /m {GUID}

This command runs successfully and returns: "Boot files successfully created".

STAGE III. Recreating BCD.

1. Removing remnants of BCD

del /q c:\boot\bcd.temp

rd /s C:\boot\

2. Creating new location

md boot

2. Creating temporary database

bcdedit /createstore c:\boot\bcd.temp

3. Adding boot manager record to the created database

bcdedit /store c:\bcboot\bcd.temp /create {bootmgr} /d "Windows Boot Manager"

4. Importing created database

bcdedit.exe /import c:\boot\bcd.temp

Here I get the error that reads:

The store import operation has failed.

The requested system device cannot be found.

What could be the problem with missing system device?

Looks as if I were trying to work with a GPT disk under a non-UEFI BIOS. However this all happens in a Hyper-V virtual machine with a GPT disk that has 2 partitions:

MSR (Reserved Partition)

and

Primary System Partition.

The primary partition has Windows 8 RTM installed on it. How do I fix that and make that Windows 8 RTM setup to boot?

When starting this VM, I get the notorious:

Boot failure. Reboot and Select proper Boot device

or Insert Boot Media in selected Boot device.

Looks like the boot code cannot be located, why?

Than

Hi,

Just make a comfirmation, have you tried guide in the link below to fix a corrupted BCD

Use Bootrec.exe in the Windows RE to troubleshoot startup issues

And information in this link can also be helpful for this issue

The cause is BIOS type.

I used to use Generation 1 VM with BIOS instead of UEFI firmware to boot from the VHD disk. This causes Hyper-V not to see the boot data, hence the "The requested system device cannot be found." while trying to create a file.

Changing the type of VM to Generation 2 (you have to create a new virtual machine, the type cannot be changed in-place) and attaching the same VHD solve the issue.
