iMac problem booting with windows partition

Help!

Just installed Windows XP using bootcamp and usually no problems switching between operation systems.

Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition.

If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

Thanks stridemat!

In the mac I set Bootcamp as startup partition and in windows, did the same for bootcamp settings.

The only improvement is now windows able to boot on restarting the system. But if I shutdown and switch on, the same problem occurs.

Seems you might need to also set the startup disk order in the Windows OS or whatever it thinks the BIOS is in its own partition.

Thanks! How to access the BIOS or similar thing in Windows?
