I'm attempting to install FreeBSD 4.8 on a system which will boot it and 
also Windows 2000 Server. I've done this with two multiboot utilities: 
the simple boot manager that comes with FreeBSD and V Communications' 
System Commander.

In both cases, I have found that when I install FreeBSD it corrupts 
neighboring NTFS and FAT partitions. After the install, the OSes in these 
partitions fail to boot or the partitions become entirely unreadable. 
Whether I tell FreeBSD not to install an MBR or whether I tell it to 
install its boot manager, the result is the same: Neighboring partitions 
are being corrupted to the point where one can not get to data on them.

I realize that dual booting is not common, but I need to do it on this 
laptop. Has anyone else on the lists encountered this problem?
