This tutorial will explain How to remove ubuntu and GRUB from dualboot system


1. Put the Windows 7 installation disc in the disc drive, and power cycle your PC after setting it to boot from CD Drive in BIOS.

2. Press a any key when you are prompted & select [language, time, currency, keyboard etc.] & click Next . Select Repair Your Computer option in the dialog window.

3. In the ‘System Recovery Options’ window Click the 1st Option Startup Repair and let it do what it wants to do, but in my case it didn’t solve the problem so I went to the next step.

4. In the ‘System Recovery Options’ dialog box, go to the last option i.e. Command Prompt .

5. Once in the command prompt (X:\Sources> ), type exactly the following commands in the same sequence

bcdedit /export C:\BCD_Backup

C:

CD Boot

Attrib bcd –s –h –r

ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

then it said

“Scanning all disks for windows installations.

Please wait, since this may take a while…

Successfully scanned windows installations: 1

[1] C:\windows

Add installations to boot list? Yes(y)/No(N)/All(A) : “

 press ‘Y’ as there was only one instance of windows installation.   Then it said The operation completed successfully.

6. Next entred the following command      bootrec /fixmbr    It said The operation completed successfully.

7. Next entred the following command      bootrec /FixBoot  Again It said The operation completed successfully.

8. Set the BIOS again to boot from the HDD and reboot.
