SBS 2008 Unbootable after partition resize – winload.exe; Status: 0xc0000225; Info: The selected entry could not be loaded because the application is missing or corrupt.

The server is all done. One last thing to do – resize that Dell OS partition now that we have the Data partition on a separate 500gb RAID1.

Being an old fashioned person (read: not a Vista user, and new to SBS 2008), I didn’t think to use Disk Management to do the resize. I used Acronis Disk Director. This resulted in the system not booting, with the above error message.

I was at a bit of a loss for what to do. I ran chkdsk from an NTFS bootdisk and this made no difference. Obviously there is no boot.ini any more, and to make matters worse, the Dell supplied SBS 2008 DVDs are non-bootable, so I was a bit stuck.

Whilst waiting the 2hrs for the SBS 2008 DVD ISO to download from Microsoft.com, I thought I’d try out a Vista disk and see if that would repair the bootmgr. It did and now all is well.

The problem is apparently caused by the UUID of the partition changing, leaving the bootmgr unable to find it, as per this article.

    after reading the above, i would like to notice everybody who tries to resize your partition/ volume on windows operating system, especially windows server operating system.
    Please do the three steps before resizing no matter which partition management software you choose: error-checking and degramentation, then back up the info.
    ok, now, you can do resizing affair
    as for the partition manager software, i listed the top three:
    1. easeus partition master
    http://www.partition-tool.com
    the cheapest one, but with best interface for all users to understand
    2. acronis disk director
    http://www.disk-director.com
    the most expensive one among these three, good brand; but features are equal as the other two’s
    3. paragon partition manager
    http://partition-manger.com
    stable, but a little bit difficult for all users to understand, especially hard to newbiews.
    hope this can help you
