How To Uninstall Or Remove Ubuntu(Or Any OS) From Dual Boot System


There is no any way to uninstall any operating system like we uninstalling any third party software. To uninstall any os you have limited option which are as follows …

1. Upgrade with newer version of  OS.

2. Format  or delete the partition.


Upgrade with newer version of  OS.

Upgrading is solution  to upgrade the system to newer version of same operating system for example upgrading from windows XP to windows 7.  To upgrade any operating system just insert the CD/DVD of latest OS  >>> Run the setup >>> chose the Upgrade option your system will be upgraded.

 Format  or delete the partition.

This option is useful for dual boot system suppose you have two operating system windows 7 and Ubuntu in your system and want to remove Ubuntu.

To remove ubuntu just follow these tips…!!

Delete every Linux partition. That would include everything – boot, swap, home, whatever way you set up your system, it is time to delete all Linux partitions. There are a couple of ways to achieve this, easiest being from within Windows’ Computer Management. You need to:


1. Log in to an account with administrative privileges.

2. Right click on My Computer, click ‘Manage’.

3. Choose ‘Disk Management’ listed under ‘Storage’ and you will see all of your partitions listed there.


Next, you need to identify Linux partitions. The Linux partitions generally don’t have a file system listed with them if Windows doesn’t recognize it, so this can serve as a clue. Other ways can be identifying by size or partition number. You can use partition managers, these are generally better at identifying files systems. Go ahead, delete the partitions, just make sure you delete the correct ones. Linux is gone and so is GRUB, which allowed you to choose operating system to use at boot time. So currently, you cannot boot into any other operating system, without some help.

                        Restore MBR

As we noted, GRUB is gone and so is the ability to boot into Windows. You would now need to boot from the Windows CD/DVD to restore the Master Boot Record. You can also use other Live CDs like one of my absolute favorites and highly recommended HBCD just in case you don’t have Windows installation media handy.    Here are the steps:

1. Boot from Windows CD/DVD and choose “Repair” when it shows up.

2. Choose command prompt on the resulting screen and run the following two commands:

3. bootrec /fixmbr

4. bootrec /fixboot

5. XP users need to run the recovery console from Windows XP CD and then type fixmbr when at the command prompt.


                                  Reclaim free space

Restart now, remove the CD and you should be able to boot into your Windows installation. Once there, you should go ahead and reclaim the unpartitioned free space which was previously occupied by Linux. Doing so is simple and straight forward:

1. Fire up Disk Management as before.

2. Right-click on the unparitioned space, choose new partition or new logical drive.

3. Specify the size and other options according to your needs and you are done.

The free space should now be accessible from My Computer like any other partition. Alternatively, you can create multiple partitions from the free space or resize existing partitions to suit your needs.You can use utilities like GParted, Easues Partition Master or any one of the many partition managers on HBCD to perform such advanced tasks easily.
