partitioning - On dual-boot iMac, after fixing "EFI Boot" issue, will booting Windows cause the same issue again?

On my dual-boot iMac, after fixing the well-known "EFI Boot" issue, will booting Windows cause the same issue again?


I'm hesitant to try booting Windows until I hear from others.


Details:


It all started when I had been working in Windows and then re-booted into Mac OSX Snow Leopard. Any attempt to boot into OSX would result in two giveaway symptoms:
1) The MAC HD was re-named "EFI Boot", and
2) a gray progress bar stopped at 10% and the spinning wheel kept spinning - no joy.


Many articles on Mac Forums describe the same thing, including the fix, which is to erasing the damaged partition and either:
a) re-install the OS from DVD, or
b) perform a Time Machine RESTORE (which I did).


Is there anything I can do to keep enjoying the benefits of a dual-boot iMac without fear of a repeat problem and associated 2-hour restore from Time Machine?
