boot - Vista/Server 2008: BOOTMGR is missing


My NTLDR recently went missing, and I was able to fix that. However, now my BOOTMGR is also missing, and I have tried all the solutions on the whole Internet to fix it. Below are the actions I've taken in the recovery command prompt:



  • bootrec /fixmbr

    • The operation completed successfully.


  • bootrec /fixboot

    • Element not found.


  • bootrec /rebuildbcd

    • Successfully scanned Windows installations.
      Total identified Windows installations: 1
      [1] C:\Windows
      Add installation to boot list? Yes(Y)/No(N)/All(A):y
      Element not found.


  • diskpart
    list disk
    select disk 4
    select partition 1
    active

    • DiskPart marked the current partition as active.


  • bootrec /rebuildbcd

    • Successfully scanned Windows installations.
      Total identified Windows installations: 1
      [1] C:\Windows
      Add installation to boot list? Yes(Y)/No(N)/All(A):y
      The operation completed successfully.


  • bootrec /fixboot

    • The operation completed successfully.


  • bcdedit /export c:\boot2
    ren c:\boot\bcd bcd.old
    bootrec /rebuildbcd

    • Successfully scanned Windows installations.
      Total identified Windows installations: 1
      [1] C:\Windows
      Add installation to boot list? Yes(Y)/No(N)/All(A):y
      The operation completed successfully.



So how do I restore my BOOTMGR without having to reinstall?


Note this question required some... interesting formatting :)


Answer



I ended up having to install Windows Server 2008 on another drive, which built a new bootloader. I updated my boot loader to select the old one only and wiped the new install so as to remain in adherence to the license.
