When asked to most of the users “How will you uninstall Linux when it is Dual Boot installed with Windows XP/Vista/7 ?” The common answers we got was “Start Windows XP/Vista/7 and format Linux Partition“. Well they were half correct, you do have to format the Linux  partition but what about the grub loader? The grub loader will still be showing you the option to boot Linux during the start up and by mistake if anybody goes for booting Linux, the system will not find any Linux on your machine and it will restart. so what can you do in this situation?

There is a simple procedure to uninstall or delete Linux completely and safely by following a step by step procedure illustrated below and it is tested by me .

Requirements:
You need a Windows XP/Vista/7 startup disk or Windows XP(verified with XP only) bootable floppy .

How to do it:

1. Boot up in Windows XP/Vista/7.

2. Start > Control Panel > Administrative Tools > Computer Management

(UAC or User Account Control in Vista/7)

3. Go to Disk Management under “Storage”

4. Select your Hard Disk and then the Linux partition.

5. Delete the Linux partition this will delete Linux and grub.

6. Now reboot your Laptop/Desktop with Windows XP start up disc or floppy and type the command “fixmbr” .

7. Above command will repair ur bootloader and rewrite ntldr which will replace corrupted grub.

8. Thats it done now boot your Laptop or Desktop normally it will be booted by default in Windows XP/Vista/7.
