Fixing "Bootmgr is missing"

This applies to Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, and Windows 8. This is a common issue that occurs when the system partition (the one that Windows boots from, not where the kernel is located) of a Windows installation gets corrupted or files on the system partition are deleted (specifically bootmgr). Resolution is fairly straightforward after booting from the Windows DVD and entering recovery mode.





Open a command prompt and use diskpart to find the system volume (usually labeled "System Reserved") and identify the installation DVD for windows (Identified for most users as the one with UDF in the Fs column and DVD-ROM in the Type column). From there, the bootmgr file can be copied back into the system partition using the copy command. The bootmgr file is located in the root of the DVD drive.Rebooting the system should allow the system to boot.

  2. While trying to replace the hard drive on my Dell Studio 1555 I came across to BOOTMGR issue and spent quite a long time to find a solution. Almost all of them were recommending the use of Win 7 installation disk. Without being able to boot the computer I didn't know what to do. Until of course I came across your posting. Which I followed and worked. I couldn't leave this page without thanking you for taking time and posting this solution in the simplest manner. While there is so much talk about the "act of kindness"on other manners, We hardly ever hear about people like you who dedicate their time to helping without any expectation. I Thank you very much for for help.
