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.

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

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.
