I've tried myself to resolve this but failed so far so I'm seeking urgent help.
I have Windows 2012 R2 Essentials installed on HP proliant DL320e gen8 with RAID1 (disk mirroring)
None of the options to restore Windows are currently viable , I've checked the array controller confinguration
and both drives are seen have thir status " OK"
Refresh PC - "The Drive where Windows is installed is locked. unlock the drive and try again"
Reset the PC - will remove all existing files
Advanced Options-
System Restore - "To use System Restore you must specify the Windows installation to restore. Restart
the computer Select and operating system, then select system restore" but cannot select an operating system
Image recovery - "Internal error occured The following information might help you resolve the error -
The system cannot find the specified file 0x80070002"
Startup Repair - "Startup Repair could not repair your PC Try advanced options to repair your PC
or shutdown or turn off your PC"
Command Prompt - booting to the command prompt only shows the "X" drive, cannot change to C: and DISKPART does not see any disks or volumes
There no option to boot with the last known good configuration.
Most things I've read point to registry corruption but there doesn't seem to be an easy way to resolve this.
I can access the drive if I remove from the server and connect it to another PC, but there is no 'repair' directory to copy from as suggested in some other posts.
Grateful for any suggestions.
