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 1^st 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) : “

I pressed ‘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.
