2nd Windows 7 OS not appearing in BIOS after reinstalling 1st windows 7 os (seperate drives)

Windows 7 not appearing in BIOS after installing windows 7 on separate drive

Couldn't find a solution to my problem in previous threads, so hoping someone can help:

I had Windows 7 installed on 2 separate drives C & G. Windows 7 needed to be reloaded on drive C. I reformatted drive C and reinstalled Windows 7 on this drive. Windows 7 works fine on drive C but I no longer have the option of choosing which Windows to load when starting up the PC.

In windows explorer everything looks intact on drive G but just need BIOS to recognise both operating systems

Please can someone point me in the right direction
