windows not booting after using easy bcd..

Hi, I have a dual-boot Ubuntu/Windows 7 Thinkpad x120 that I'm trying to remove Ubuntu from (decided running Wubi is sufficient for my purposes). I used EasyBCD (The Non-Geeks Guide To Safely Uninstall Ubuntu From A Dual-Booting Machine) to write MBR. Now Windows won't load! I get an error Windows failed to start... 1. Insert your Windows installation disc... 2. Choose your language.. 3. Click "Repair your computer" If you do not have the disc, ... File: \Boot\BCD Status: 0xc0000098 Info: The Windows Boot Configuration Data file does not contain a valid OS entry. The Operating System Recovery Disc from lenovo (thanks Lenovo for sending it) boots to Lenovo Rescue and Recovery 4, or in "Safe mode with command prompt" but immediately crashes. Any advice on what to do?? Many thanks.
