Where to install Norton Ghost

Please forgive this newbie question.

 

I have a computer with 6 drives.  Drive C is the main (system) drive on which the Windows OS is installed.

 

I wish to be able to make a copy of the complete drive C and store it on drive G.  There is ample room.

 

I know how to do this, assuming I install Ghost on to the C drive.

 

But...if the C drive is corrupted and I wish to restore the whole drive from the backup copy. how can I do so if the Ghost program is on the C drive and inaccessible because the C drive is not accessible..

 

Does Ghost allow me to make a recovery disc with some sort of OS on it?

 

Would it be better to install Ghost on an external or a USB drive?

 

I am so sorry for taking your time if this is a simple question.

 

Thanks in advance for your help.
