Most of Grub's files are outside of the MBR - these essential files won't be 
accessable after the Linux drive is upgraded.

I can't see a solution other than re-installing Grub with the new drive in 
its final location.  It would be prudent to ensure that you have a Windows 
boot floppy, so that you can restore the Windows MBR, if necessary.

It would work.   If you have a recent BIOS, which can exclude "C" from the 
boot list and include "D", you could then install Grub on BIOS "D" drive.  
Failing that, you would soon be faced with over-writing the Windows MBR on 
the BIOS "C" drive with Grub anyway and might as well install just Grub

Grub can be installed from a Grub boot floppy - that would avoid the chicken 
& egg situation of having to be able to boot RH, to install Grub.
