Need to rebuild MBR
Windows Key plus 'C', select Settings, Power and whilst holding down your Shift Key, select 'Restart'
Select 'Troubleshoot', then Advanced', then 'Command Prompt'
Computer restarts, select your Account and enter your Account Password
At the CMD prompt type bootrec /ScanOs then Enter (Note space before switch /)
If all is in order you should see both Operating Systems, note location of each.
Type bootrec /RebuildBcd then Enter
This should allow you to add Windows 7. Once done type exit then Enter
Reboot your machine.
