Which command can I use overwrite the boot loader?

Question

Grub was installed onto my machine as part of an Ubuntu installation. I'm now reverting my machine to be Windows only, and so no longer require the Grub boot loader. How do I remove Grub?

Answer 1

Once upon a time, all you needed was to boot into Windows and run this on the commandline:

C:\> fdisk /mbr

But not anymore. You'll need to use the Windows Recovery Console (from a Windows boot/install CD). So you need to boot into the Recovery Console and run this:

> fixboot

Or this:

> fixmbr [device]

Use the MAP command to find the correct [device] parameter.

On Vista? EasyBCD did it for me. Literally one click, was very impressed. For XP, somebody else'll have to chime in.
