I use EasyBCD to manage my tripleboot of (1) Windows Server 2008 R2, (2) Windows 7 Professional and (3) Ubuntu Linux. While trying to change the order of my boot menu I ended up losing the Windows Server entry. Luckily I had a boot menu backup (.bcd file) that allowed me to restore my boot menu using EasyBCD.

However, when I now select the Windows Server option in my boot menu the Windows Server Recovery Environment starts up. So I have to select language/keyboard layout/etc. and then I have 3 options as shown in the image below.

System Recovery Options.

My goal is to fix the one corrupted Windows Server entry from my boot menu without messing up or losing the two other ones.

I'm guessing the Recovery Console (Command Prompt) is the next step and that I will be needing bootrec.exe. But when consulting this page: Use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows (about half way down there's a link that shows the bootrec.exe options) I'm getting uncertain.

The page lists 4 options for bootrec.exe :

  • /FixMbr
  • /FixBoot
  • /ScanOs
  • /RebuildBcd

What option do I need to fix just the server entry of my boot menu?

Thanks in advance,

Sander

P.S. All three OS's are on the same physical disk (3 different partitions). Disk layout:

  1. System reserved (primary partition, 100 MB)
  2. Windows 7 (primary parition, 150 GB)
  3. Windows Server 2008 (primary partition, 150 GB)
  4. Extended partition (linux partitions (/,/swap,/home), 150GB + data partition, 150 GB)

P.P.S. This is what my boot menu looks like using EasyBCD (Detailed/Debug mode) on my Windows 7 installation.
