Hello TechNet, One of my ProLiant web servers appears to have bit the dust. I'm getting a "Boot MGR Missing" message during startup. I've since found that there is no "Repair" option on the Server 2003 disc or Safe Mode option from POST. I cannot do anything except reseat the RAID controller cable, RAM, etc. That has yet to help. I performed a number of CHKDSK's, System File Check's (SFC's), and HP Insight Diags/Array Diags, but to no avail. Any thoughts for the quickest way to repair this boot manager? I know in 2008 R2 you can use the Bootrec commands. Are those available in 2003 R2? Thanks in advance. Josh

Hi, In earlier versions of the Windows operating system that run on a basic input/output system (BIOS)-based computer, such as Windows XP, the boot process starts with the system BIOS. The BIOS determines the boot device, and then loads the first physical sector. This physical sector is named the master boot record (MBR). When Windows Vista or Windows 7 starts on a BIOS-based computer, the BIOS loads the MBR and then loads the boot sector. However, boot code loads the new Windows Boot Manager program (Bootmgr). So, I would like to confirm that install operating systems in a dual-boot configuration? If so, please refer to the following Microsoft KB article to fix the issue.
