b) Select the correct keyboard input method and click ‘Next’.

Note: If you are using the Windows7 Install DVD then at the 'Install Now' prompt (Do not pick the Install Now option) instead choose the 'Repair your computer' option located in the lower left of the display.

c) The System Repair tool will search for a valid operating system and will report that “Windows found problems with your computer’s startup options. Do you want to apply repairs and restart your computer?”

d) Click ‘Repair and restart’ and reboot again to the Windows 7 System Repair environment.

e) Click ‘Next’ at the keyboard selection prompt and when the ‘System Recovery Options’ screen appears verify that the “Use recovery tools that can help fix problems starting Windows” is selected.

Note: On a Dual Boot system there may be only one operating system listed if you have removed one of the two versions of Windows 7. Click the ‘Next’ button.

f) Now from the menu list select the ‘Command Prompt’ option.

g) At the DOS prompt type the following four commands:

bootrec.exe  /fixmbr

bootrec.exe  /fixboot (may return an 'Eliment not found' message)

bootrec.exe  /ScanOs  (Optional)
The /ScanOs option scans all disks for installations that are compatible with Windows Vista or Windows 7.
Additionally, this option displays the entries that are currently not in the BCD store.
Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.

bootrec.exe  /RebuildBcd

h) Close the command prompt window and click the ‘Startup Repair’ option.

i) The repair process may take some time, so wait until the process completes at which point you will see two messages

“Windows cannot repair this computer automatically” and “Startup Repair cannot repair this computer automatically”.

These messages are the result of the radical changes made by removing the other drive. Ignore the Send/Don’t send options.

Note: Please perform step j as detailed below, startup repair must be run multiple times (At least 3 times).

J) Close this message window by clicking on the X in the upper right corner of the Send/Don’t send window. Next click on the ‘View advanced options for system recovery and support’ option and from the main menu once again click ‘Startup Repair’. This time the repair process may only that a few seconds and when prompted “Startup Repair could not detect a problem”, click ‘Finish’  and run the ‘Startup Repair’ option one more time, click ‘Finish’, and then remove the System Repair DVD and click ‘Restart’.  Reboot the computer.

Test your drive - Create a Bootable CD:
Anywhere from 5 to 25%, (depending on the manufacture and model) of new hard drives are defective.
Note: Hard drive reliability has gone way down in the last 18 months.

Test your drive using the drive manufacture's utility.
If you have a new Seagate hard drive the very next thing would be to download Seagate's Seatools
(the bootable CD) and check for bad sectors.
