This is my scenario:
Right now I have an 80GB and a 20GB hard drive in my machine. Each has a single partition occupying the whole drive. The 80GB boots Windows 2000 Pro and the other is an extra drive for data.
What I want to do, is partition the 20GB into two 10GB volumes, and on one volume install Windows 2000 and on the other Windows XP. I plan to use a third party boot manager. And I want the 80GB to be used just for data - shared between the two OSs.
But knowing nothing about user permissions, NTFS security, etc. I'm concerned that I won't be able to access all my files on the 80GB with both new OS installations. What's the score? I could really do with some help.
