LILO is simple, but pure and works well
Win OS first, don't share files unless you really, really have to.
SuSE could see some (non-encrypted) NTFS content
Do not expect the isolation to protect the Linux side from Windoze virii, etc. it will not.
Those files are on the machine and will list and can be subject to malware.
I am looking into a Tiger / WinXP box, to be kept off-net for Audio and personal stuff.
Separate harddrives for each OS.
Current box is becoming a Torrent Seeder & FTP server
and an old lappy becomes my email, chat, & surf virus catcher... hmm, I migh run ubuntu on it, for kicks... SuSE seems to be going strictly commercial
