Esta es la solucion a un problema que tuve con el booteo de windows server 2008, el cual estaba instalado en un disco IDE (c:) pero el sistema operativo esta instalado en un disco serial ATA (d:), por error se elimino la particion del disco C: y el sistema no encotraba el arranque.

Not what you want to see when trying to boot Windows Vista Server…oops,
sorry, I mean Windows Server 2008.  🙂

Unfortunately, this is what I encountered recently after a Windows Server
2008 virtual machine rebooted following some routine Windows Updates.  After
some time spent troubleshooting, it did not appear that any of the updates
themselves had caused the problem.  The type of backup system in use for this
server allows me to boot virtual copies of the backups from any 15 minute
interval in the previous 2 days.  I was able to boot a virtual copy of this
server from the backups before the updates were installed.  It had the same
“bootmgr is missing” error.  And the server had rebooted successfully 5 days
ago, so something in the past 5 days after that last reboot caused this
problem.

Research (googling) on the ‘bootmgr is missing’ error led me to this
Microsoft KB article pretty quickly:

http://support.microsoft.com/kb/927391

Here is the content of that article:

Cause:

This error occurs when either of the following conditions is true:

  • The Windows Boot Manager (Bootmgr) entry is not present in the Boot
    Configuration Data (BCD) store.
  • The Boot\BCD file on the active partition is damaged or missing.

Resolution:

Method 1: Repair the BCD store by
using the Startup Repair option

You can use the Startup Repair option in the Windows Recovery Environment to
repair the BCD store. To do this, follow these steps:

  1. Put the Windows Vista installation disc in the disc drive, and then start
    the computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, and a keyboard or another input
    method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click
    Next.
  6. In the System Recovery Options dialog box, click
    Startup Repair.
  7. Restart the computer.

Method 2: Rebuild the BCD store
by using the Bootrec.exe tool

If the previous method does not resolve the problem, you can rebuild the BCD
store by using the Bootrec.exe tool in the Windows Recovery Environment. To do
this, follow these steps:

  1. Put the Windows Vista installation disc in the disc drive, and then start
    the computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, and a keyboard or another input
    method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click
    Next.
  6. In the System Recovery Options dialog box, click
    Command Prompt.
  7. Type Bootrec /RebuildBcd, and then press ENTER.
    • If the Bootrec.exe tool runs successfully, it presents you with an
      installation path of a Windows directory. To add the entry to the BCD store,
      type Yes. A confirmation message appears that indicates the entry was added
      successfully.
    • If the Bootrec.exe tool cannot locate any missing Windows installations, you
      must remove the BCD store, and then you must re-create it. To do this, type the
      following commands in the order in which they are presented. Press ENTER after
      each command.

      Bcdedit /export C:\BCD_Backup
      ren c:\boot\bcd bcd.old
      Bootrec /rebuildbcd
  8. Restart the computer.

Method 3: Rebuild the BCD store
manually by using the Bcdedit.exe tool

If the previous method does not resolve the problem, you can rebuild the BCD
store manually by using the Bcdedit.exe tool in the Windows Recovery
Environment. To do this, follow these steps:

  1. Put the Windows Vista installation disc in the disc drive, and then start
    the computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, and a keyboard or another input
    method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click
    Next.
  6. In the System Recovery Options dialog box, click
    Command Prompt.
  7. Type the following command, and then press ENTER:
    cd /d Partition:\Windows\System32

    Note Partition represents the letter of the
    partition on which Windows Vista is installed. Typically, this is partition C.

  8. Type the following command, and then press ENTER:
    bcdedit /enum all

    In the Windows Boot Loader section of the output from this command, note the
    GUID that is listed for resumeobject. You will use this GUID
    later.

  9. Type the following command, and then press ENTER:
    bcdedit -create {bootmgr} -d “Description

    Note Description represents the description for
    the new entry.

  10. Type the following command, and then press ENTER:
    bcdedit -set {bootmgr} device partition=Partition:

    Note Partition represents the letter of the
    partition. Typically, the letter is C.

  11. Type the following command, and then press ENTER:
    bcdedit /displayorder {GUID}

    Note GUID represents the GUID that you obtained
    in step 8.

  12. Type the following command, and then press ENTER:
    bcdedit /default {GUID}

    Note GUID represents the GUID that you obtained
    in step 8.

  13. Type the following command, and then press ENTER:
    bcdedit /timeout Value

    Note Value represents the time in seconds before
    the Windows Boot Manager selects the default entry that you created in step 12.

  14. Restart the computer.

If you are booting from a Server 2008 install disk, when you use the “Repair
your computer” option, the available options look like this:

You can access the repair option on a Server 2008 disk by choosing “command
prompt”, then running  “x:\sources\recovery\StartRep.exe”.

I did this and it worked like a champ!  It found an error, corrected it, and
the server was back up and running 10 minutes later.

I have also done this on Server 2008 using a Windows Vista install disk.
Slightly risky, but the server was down anyway, and I was in a pinch.  That also
worked.  Along the same lines, I would guess that a Windows 7 install disk would
work for Server 2008 R2 if you had no other option.  But don’t hold me to
that!
