Hi,

I am new here, and I have successfully installed Dual Boot Windows 7 and Kali.
I used a bootable USB with the Kali image (DVD Rom is not working)
But after the successful installation of Kali,I am unable to boot to my old Windows 7.

I get this error message:

got this error message:
“Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:

1. Insert Windows installation disk (etc)
2. Choose language settings
3. Click “Repair your computer”
"

Any ideas? Do I need to find a Windows installation Disk?
