This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Here is a tutorial how to fix it. Try it hopefully you will get what you want.

UPDATE AS Comment says

1: Insert your bootable media whatever you have like Windows 7 DVD or USB. 2: Boot from the bootable disc or USB. 3: Instead of click on Install Now select the option given bellow on dialog box Repair. 4: Select the Startup Repair option.

5: Now click on Startup Repair. Run the startup repair and it will attempt to fix this issue.

If it doesn't work, follow step 6.

6: Click on Command Prompt.
A) Type c: and press Enter.

C:\ is the drive letter where Windows 7 is installed. You may replace it with whatever drive letter you want where you have installed Windows 7.

B) At the C:\ prompt, type cd boot and press Enter.

C) At the C:\Boot prompt, type the following commands and press Enter after each command. bootrec /RebuildBcd
bootrec /FixMbr
bootrec /FixBoot

enter image description here

Now close the command prompt, remove the DVD and reboot your computer.Best of luck.

You have any backup image on your external hard drive or on DVD. – avirk Aug 23 '11 at 14:46
And have you did it just now to fix it or before I suggest you the repair. – avirk Aug 23 '11 at 14:47

you might be able to undo the formatting with testdisk - there's a few questions about this on SU – Journeyman Geek Aug 23 '11 at 15:33

To repair your BOOTMBR:

  1. Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click Next.
  6. In the System Recovery Options dialog box, click Command Prompt.
  7. Type "Bootrec.exe /FixMbr", and then press ENTER.

I've done this several times after having problems with Grub and linux installation.
