hard drive problem

I have a hard disk problem that is nagging at me.
I have a HDD in the PC (local disk (F)) now i can drag and drop to it or copy and paste without any problem, i am able to use it just as any normal disk except if i try to use the "send to" function and then is does not show up in the menu.
If i try to set it as active with my manager it give the message that the PC may not boot if i proceed (see photo)
It also shows healthy in disk manager.
My OS is Windows 7 ultimate.

Any ideas please.

 

So the send to function doesn't appear or doesn't work from your desktop?

 

The "send to" function is there but if i click it the hard drive is not there.
