I have Ubuntu 12.04 LTS and Windows 7 Home Premium on my laptop. My desire is to uninstall Ubuntu without spoiling MBR and Windows 7.

I would like to emphasize that Ubuntu was installed later so I select the OS in GRUB. I would also like to uninstall GRUB. How can I do so in a painless and simple manner?


In Windows you can use "Dual-boot Repair" tool. Rewrite all partition boot records and MBR.

Or from Windows 7 recovery/installation CD/DVD/USB run on command prompt:

bootsect /nt60 ALL /mbr

Or you could just run "StartUp Repair" from Windows 7 recovery CD. Eventually you have to run StartUp Repair more then once with rebooting after each run to check if problem is fixed.


I would do something like the following steps if I were you:

  1. Backup any valuable data on your Ubuntu system
  2. Boot into a Windows 7 installation disc
  3. Repair your system by overwriting the MBR (Master Boot Record)
  4. Boot into Windows 7
  5. Format the Ubuntu partition(s)

By overwriting the MBR and formatting the Ubuntu partition(s) you are effectively "uninstalling" GRUB and Ubuntu, although there's no such thing as uninstalling them - only writing over previous data.

  • Thanks, that sounds worth trying. Why I cannot erase GRUB, isn't there an option to do so? – Vesnog Oct 18 '13 at 11:12
  • @Vesnog Overwriting the MBR is erasing GRUB because GRUB lives there. See en.wikipedia.org/wiki/GNU_GRUB#Booting. – user13742 Oct 18 '13 at 13:35
  • Okay, I understood now. – Vesnog Oct 18 '13 at 13:46

You can use EasyBCD for safely uninstall.

  • In which OS should I use this program? – Vesnog Oct 18 '13 at 11:15
