How to recover a Boot Record in Windows?

The boot record stores the first bits of software executed once the system BIOS hands control of the computer over to software.

  2. When prompted, press R to repair a Windows XP installation.
  3. If repairing a host with multiple operating systems, select the appropriate one (XP) from the menu. If you have only one operating system, enter 1 to select it.
