Multiboot – W2K – access to HDD

I am working on Dell Inspiron 8000 with 20Gb harddisk. I created a partition (c:\) with W2K Pro, another partition (e:\) with W2K Pro and a third (f:\) with WXP Beta2.

When I boot the W2KPro on the c:\-drive i do not have access to the other drives, as I want it to be.

But when I boot the W2KPro on the e:\ or the XP on the f:\ I have access to the c:\. I do not want to have access to the c:\. I want the three configs to be seperated completely.

How can I solve this problem.

Tx.
