Answer #1
see if you can do a system restore back to an earlier time ( before you loaded that magicdisk program ), by using mini windows xp
Answer #2
You can do a Startup repair using your Windows 7 install disk..
Or use the command line prompts as shown here..

Answer #3
you should set the default boot to be your hard drive. it might be the vhd is set as primary. This can be done in command prompt using diskpart.
