My apologies if this is covered elsewhere. I've seen plenty of difficulties posted and I want to avoid those by doing it right, from scratch. I have not yet installed Vista... I have two HDs: C: XP Pro SP2, with Disk Director, but OSS is not installed/active. D: Empty. This is where I will install Vista. What's the best way to proceed so I have a dual boot system with XP as default, using OSS? Thanks!
