This tutorial explains how to remove linux operating system safely from your Dual boot systems(i.e. windows and linux both are installed on that computer).

Linux operating systems are pretty good. and because they are free and eaisly available we always want to try a new one. But at the sametime we dont want give up our favorite windows operating systems. so we choose to have a dual boot system where we can switch to any of the OS easily. But when we want to remove Linux OS and return to window we come across a problem that windows cant find MBR (Master Boot Record). To overcome this problem we have to restore MBR. To do this just follow these steps:

First of all you need to know where your Linux OS is installed to,i.e. what drive it is currently living on?
Then next thing is to restore that partition used by Linux to windows. To do this:

    1.Click Start > Control Panel > Classic View > Administrative Tools > Computer Management.
    2.Click Storage > Disk Management.
    3.Select the Linux partition, right click and select Delete volume option to delete linux and grub.
Once you have followed this through, you will now have free space.
Once you have formatted the drive, you need to reformat it to your required file system type. either Fat32 or NTFS.
Now the important part is coming up...!!!

Fixing your Master Boot Record to make Windows Bootable again.

    1.Boot up with the Windows CD.
    2.Restore your Master Boot Record (MBR) by using the following command:
        a.If using a Windows 98 CD, boot into command prompt and enter: fdisk /MBR
        b.If using Windows 2000, XP, 2003 CD, enter into “Recovery Console” by pressing “R”, and
          enter: fixmbr
       c.If using Windows Vista, Server 2008, Windows 7 CD, click on “Repair Computer” link, then click on “Command Prompt”.

Navigate to your CD drive by using cd  command and
enter: bootsect /nt60 SYS /mbr
 3.Exit from the command prompt and press Enter or restart your computer.

There will be no Grub shown and you will directly boot into Windows. This is how you will return to a normal window operating system from a dual boot system.

Thanks...!!!
