I'm trying to repair my master boot record but when I try to access the repair my computer option using the DVD, it doesn't come up.... Instead goes straight to the drive options.

Anyone seen this before?

Here's How:

1. Boot your computer to the Windows 7 DVD (or to a "Repair CD"). At this screen choose to install now.
25672d1251414873-mbr-restore-windows-7-m
 
2. Select your language and click next.
25673d1251414836-mbr-restore-windows-7-m
 
3. Click the button for "Use recovery tools".
25674d1251414836-mbr-restore-windows-7-m
 
4. Then select "Command Prompt".
25675d1251414836-mbr-restore-windows-7-m
 
5. When open, the command prompt will look like this:
53598d1251414836-mbr-restore-windows-7-m
 
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
53601d1251414836-mbr-restore-windows-7-m
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

25680d1251414836-mbr-restore-windows-7-m
 

11. Then you can reboot your computer into Windows.
