I want to set up a dual boot with Win2k (primary partition) and XP (secondary partition). I have a 45 gig hard drive with a large logical storage partition that i want to leave alone. It takes up about half the drive right now. I want the cleanest possible boot partition. I've read a few things about fdisk /mbr. Can I quick format my boot partition and do a fdisk /mbr - will this give me a clean boot partition while preserving my extended partition, or would i lose my extended partition? The reason i'm asking is because i'm not familiar with fdisk /mbr and/or exactly what it does. Any help would be appreciated, thx.
