Error Loading Operating System Windows Server 2003
Posted on 2013-01-26
I have a server with a RAID 5 array. It has two disk partitions set up as dynamic disks, one set up as drive letter C:\ and the other as drive letter I:\. I needed to shrink the size of the I:\ drive in order to make more space to increase the size of the C:\ drive that was running out of space. I used the AOMEI Dynamic Disk Manager Server Edition to resize the partitions.
The Dynamic Disk Manager shutdown the system, proceeded to make the resizing changes, and reported that it had successfully made the changes. Upon rebooting the system, I got the dreaded "Error Loading Operating System" message.
I promptly booted my Windows Server 2003 OS disk into the recovery console. I am able to see files on both partitions, including the c:\Windows directory. I figured the master boot record was corrupt, so I ran the "map" command and saw this output.
c: \Device\harddisk0\partitio
I: \Device\harddisk0\partitio
I then ran the command "fixmbr \Device\harddisk0", and then rebooted. I still got the "Error Loading Operating System" message. I then went back to the recovery console and ran "fixboot c:". Rebooted and still the dreaded error message.
I next try booting my Windows Server 2003 OS disk and perform a repair installation of windows. I can see the disk activity as data is being written to the disks. The repair install completes and I reboot, and the "Error Loading Operating System" message still appears.
This still looks like a broken MBR, but I don't know how to correct it. Can anyone provide a solution?
Thanks!

Did it convert the disks into basic type? Or are they silk dynamic? If they then your fixboot and fixmbr commands are not working because they do not work on dynamic drives.
Is the system partition set active?
Is the system partition set active?
I did not convert them to basic. I left them as dynamic. That might explain why I cannot get fixmbr to work. What commands should I run to check that they are dynamic? Should I convert then to basic, or is there another way to fix the MBR? How do I convert the drives to basic with only the recovery console?
Thanks!

You cannot convert them to basic via recovery console. You need specific software for this.
Lets do it as follows:
Download trial version of Drive Backup 11 Server from here: www.drive-backup.com
Then install it and run on any working machine. In Tools find Recovery Media Builder.
Prepare a cd with it. Boot the problem server from it and select normal mode.
There run Drive Backup. Does it see the RAID as single HDD with 2 volmes?
If not reboot to the same cd but select Safe Mode.
There start Drive Backup right click on drive and select Convert to Basic.
After that run Boot Corrector and update there MBR and partition boot record.
restart to Windows.

Thank you very much. That worked. I don't usually use dynamic disks, and didn't realize that fixmbr didn't work on dynamic disks.
