How to Restore the Windows 7/8 using MBR (Master Boot Record)

Recently, one of my friend installed Ubuntu 12.10 alongside windows 7 and windows 8 in a  separate partition in his laptop. Later on, after 2 days to uninstall Ubuntu, which he doesn’t know how! he deleted the partition and after restarting the system he got an error which shows like this:

error:No partition found

GRUB not found>

 

then he came to me for the solution, what he has to do if the above two lines pop. Actually the problem here is Ubuntu Partition is deleted and thus the Grub boot-loader so the system doesn’t know where it has to search. Below are the steps one has to do, to solve the above probem and it goes as follows:

 

1. Boot your computer to the Windows 7 DVD (or to a “Repair CD”). At this screen choose to install now.

2. Select your language and click next.

3. Click the button for “Use recovery tools”.

4. Then select “Command Prompt”.

5. When open, the command prompt will look like this:

6. The command we will use, bootsect.exe, is in a folder (named boot) on the DVD.

We need to know what drive letter has been assigned the DVD drive to access the folder.

Code:
Type: diskpart
and press Enter

Type: select disk 0 (zero)
and press Enter

type: list volume
and press Enter

In this screen shot, the 7 DVD is letter: G

7. Use your DVD drive letter and

Code:
Type: exit
and press Enter

to close Diskpart

Type: G: (use the letter of your DVD drive)
and press Enter

Type: cd boot
and press Enter

Type: dir
and press Enter

to verify that bootcect.exe is there (if you really need to)

8. To restore the “bootsector code”:

Code:
TYPE: bootsect /nt60 SYS /mbr
and press Enter

NOTE: If this method fails to restore the MBR, you can try the bootrec command as it is also a tool for repairing the MBR.

9. When completed successfully,

Code:
Type: exit
and press Enter

This will close the command prompt window.

10. Now select Shut Down or Restart

11. Then you can reboot your computer into Windows.
