I'm new to Oracle ASM and have a question.

If I create Oracle ASM partitions on a basic disk that already contains the Dell Utility Partition (FAT) and System Partition (C: NTFS, boot partition?) on Windows 2000, will the subsequent ASM "automatic disk mounting" and ASM "disk header writing/labelling" cause any trouble to the system/booting?
I ask the question because the physical disk also hosts the system C:.
