What command is used by Windows 2000XP to replace the Master boot program program with a fresh one?

Answer 1

To fix the Master Boot Record on a Windows 2000/xp computer you must:

1. Boot to the install media

2. When prompted, choose Repair. ultimately, you'll access the Repair Console

3. If necessary, log into your Windows application

4. There is a utility on the install media called FIXMBR.exe, On the command prompt, type FIXMBR and press enter.

When Windows is installed, it creates the Master Boot Record on the first sector of the first hard drive. It makes a second copy or backup of the Master Boot Record immediately after the original on the hard drive. FIXMBR copies this backup copy of the MBR to the MBR location.

If you still cannot boot, repeat steps 1-3 above:

4. There is a utility on the install media called FIXBOOT.exe. on the command prompt, type FIXBOOT and press enter.

When FIXMBR fails to restore the Master Boot Record, FIXBOOT will read the information of the install and rebuild the master boot record from scratch and install it on the first sector of the hard drive. It will also create the backup.
