After I wiped out my Ubuntu partition in order to get some extra space for my Windows 7. I got following message when I restart my computer :
error: no such partition
grub rescue>
I found the resolution on Microsoft's website after googling for a bit and it's quite easy. Just follow these steps :
a) Insert the Windows 7 System Repair DVD or Installation DVD and reboot.
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 dispay.
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 that on your Dual Boot system there now should be only one operating system listed. Click the ‘Next’ button.f) Now from the menu list select the ‘Command Prompt’ option.
g) At the DOS prompt type the following three commands:
bootrec.exe /fixmbr
bootrec.exe /fixboot (may return an 'Eliment not found' message)
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.
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.
