click here for the full story but now something very bizarre has happened!! I done as paperman27 suggested and backed up and started afresh. I installed 2000 over XP on 'C' then XP over 2000 on 'D' now I have 3 options on boot up. The new install of 2000, a new XP and a third which is my old XP and I can access all 3 ok. But my harddrive only seems to be in 2 - C and D. Whats going on!!
