Recovering from a physical server failure on to Hyper-V running Windows 2008 R2 SP1. Single volume in the backup, restore from network share which completes successfully. Have ensured drive size is provisioned as larger then physical drives. Restore completes successfully but is allocating 100mb system partition to C: and my OS partition to D:. On reboot it flashes up with a stop 0x0000007B error.
I've tried a number of different things from posts but must be missing something here. In regards to the swapped drives I following the instructions to modify bcdedit changes as follows: https://support.microsoft.com/en-gb/help/2261423/error-message-when-you-restart-windows-server-2008-r2-after-you-perfor
The bcdedit changes seem to apply ok but the drives are still swapped after reboot. Manually changing in diskpart and regedit (per: https://support.microsoft.com/en-us/help/223188/how-to-restore-the-system-boot-drive-letter-in-windows ) also doesn't seem to fix the swapped drives.
I believe the 7B error could be due to disk drivers on the physical server but I was trying to address the drive allocation error first, however strangely enough after making the above bcdedit changes it looks like the 7B error isn't flashing on startup anymore.
Appreciate any guidance on the drive letter issue. From other servers system partition should be hidden with no drive letter and OS should be C: but can't seem to get any changes to stick. Happy to share any details as needed. Thanks.
