How to: remove Ubuntu grub in dual (or more) booting computer

Tags:

My laptop is dual boot. One Windows XP SP2 and the other is Ubuntu 10.04. I'm using Ubuntu default boot manager, which is Grub 2.

This is the partition info:
hd0,1 : Windows XP (NTFS)
hd0,5 : Partition for data (NTFS)
hd0,6 : Ubuntu (Ext3)

Yesterday, my little sister borrow it to, you know - "facebook-ing" using Windows XP. Somehow she formatted by Ubuntu partition by accident. Next morning I woke up with these:

Grub loading
error unknown filesystem
grub rescue>

A quick check shows that my Ubuntu partition is now empty and the partition type is NTFS, oh my gosh...

In order to get to Windows, I need to remove the grub bootloader. These are my steps to remove the bootloader:

  • Boot the laptop using Windows XP install disk.

  • Choose Recovery when asked -- press "R".

  • After logged in to the recovery console, choose the Windows installation.

  • Enter your administrator password when asked.

  • Execute the following command: 
    fixmbr

  • Reboot the laptop.

  • Done.

Good luck!
