Bootrec.exe, available as part of repair from the command line can resolve a number of start up issues on Windows.  It comes in quite handy for replacing the master boot record (MBR) and boot loader (a good way to remove a multi-boot manager like GRUB).

 Be sure you understand what you’re doing it you choose to use it.

 Use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows
