Windows Vista includes a new Boot Manager (BootMgr) that replaces the old NT Loader (Ntldr).

If the boot partition no longer can be found, then Vista will display the following error: BOOTMGR is missing. Press Ctrl+Alt+Del to restart

The Windows Boot Configuration Data file is missing required information

This can usually be solved by checking the boot devices, and if no problems found then use Windows Recovery Environment (WinRE) and perform a "Startup Repair".

If by accident having compressed the entire boot partition, then Vista will display the following error: BOOTMGR is compressed. Press Ctrl+Alt+Del to restart
This can usually be solved by using Windows Recovery Environment (WinRE) and perform a "Startup Repair". If that fails then use WinRE to enter the "Command Prompt" and execute these commands:

  • compact /U C:\bootmgr
  • compact /U C:\ntldr

Insert installation dvd
Click repair my computer
Try letting it fix it by using the startup repair
If that fails then cancel till you reach the menu where you can select the c: prompt.

Now write cd\Windows\system32
Then you have to use the bootsect
