I am currently using Windows 8, but the previous version of my Windows 7 is still present and i've not deleted it. It is in the D:\ drive.
But the Windows 7 OS however is not in the boot menu, and Windows 8 by default is getting loaded.
I've tried seeing in msconfig, however i didn't find Windows 7 in the list of available Operating Systems.
Now how can i add the Windows 7 to boot menu. I want that back!
