We had an issue recently with one of our Windows 2008 R2 servers , where after reboot the server did not come back up and showed the following error “BOOTMGR is Missing”

I fixed the by recreating the Boot Configuration Data Store.

  • Insert 2008 R2 media and boot onto it
  • Choose Repair and System Recovery Tool
  • Choose Command Prompt
  • Run the Following commands
    Rename c:bootBCD bcd.old
    Bootrec / RebuildBcd
    Bootrec / FIXMBR
    Bootrec / FixBoot
    Cd “X:Sourcesrecovery”
    StartRep.exe
  • Reboot Server and all should be ok
  • If Server has the Hyper-v role installed make sure to run “bcdedit /set hypervisorlaunchtype auto” and reboot.

After this all should be up and Running Smile
