Repairing SBS 2008 Boot

Posted on 2011-04-30

Hi folks,

Got a Windows SBS 2008 machine. Prior to SBS 2008 being installed, there was a failed attempt to do an upgrade from SBS 2003. Somehow, that left an option for Server 2003 setup in the boot options, and whenever the system boots, it is defaulting to that choice. You have to be watching when the boot screen pops up, and manually select SBS 2008, to get into the correct selection.

I have been trying to get rid of that other option, or at least get it to default to the correct one, so that if a reboot happens while no one is at the server, it will still load the right OS. So far, though, I've had no luck. And now, I'm afraid, I've made a mistake and messed things up further.

Using bcdedit.exe, I've been trying to set the proper options. I have now managed to delete the {bootmgr} option from the list of enumerated options, and nothing will boot any longer. I used the SBS 2008 install disc to attempt a repair, but it sees no Windows installations at all for me to repair. If I skip past the auto-repair and just go to a command prompt, I can access the hard drive and see all of the files, but the auto-repair says it can't identify any Windows installs.

    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:

    - Get your Vista installation DVD and pop it into your drive.
    - Then restart your computer.
    - Press a key when you are prompted.
    - Select a language, a time, a currency, and a keyboard or another input method, and then click Next
    - Click Repair your computer
    - Click the operating system that you want to repair, and then click Next
    - In the System Recovery Options dialog box, click Command Prompt
    - Type bootrec /rebuildbcd and then press ENTER

    • If Bootrec runs successfully, it will present you with the 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 Bootrec 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 shown below: (Remember to press ENTER after each command)

    bcdedit /export C:\BCD_Backup

    ren c:\boot\bcd bcd.old

    bootrec /rebuildbcd

    - Restart the computer.
