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?

I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key.
