Yes and No.

Mandrake does a good job with XP/2000 , but not all other distros do so well. Grub also work better than Lilo.

If each stand alone this is fine, but as Linux cannot yet write to NTFS partitions and Windows WONT write to linux partitions. You need to be creative and make an additional fat32 partition which both can mount ( I auto-mount as /home/user/shared) and keep shared files in there. (Of course windows just calls it D:\

At least that's how I get it done for now. So far it has worked well...... Dose this constitute a tweak ???

I've put Mandrake 9.1 on 2 dual boot machines (1 with 2000, 1 with XP) 
and it didn't require any tweaking.

The only requirement is that the order of installation is important. You 
have to partition the disk first then put windows on one partition, then 
Mandrake on the empty part of the disk. Mandrake finds the windows 
partion(s) and puts an entry in lilo for it.
