I'm currently running XP Pro on partition C, with my XP programs on D, data on E and I use F for video editing files. On H (G is my DVD drive) I am running Windows 7 Evaluation copy, build 7100. I have ordered 7 and will receive it in about 3 weeks. I understand that I would need to do a clean install of 7 and I'm assuming that as the eval copy needs to come off anyway, I would backup all my 7 data files etc and then format that partition (H) and install the release Windows 7 there. Am I right in thinking that the dual boot will still work as now or will there be a problem? I also plan (when I am happy with the new 7 setup) to do a clean install of XP Pro to clear out 2 years junk and unwanted programs and just instal the remaining programs that I haven't put onto Windows 7. I still have a few that don't work in 7, hence keeping XP Pro. Some clarification would be very useful here as it might be a bit fraught as it is! I'm using a core 2 duo E6600 with 2gb ram and 7 has been running very well for several months, long enough for me to feel confidant about purchase, not like Vista which I did not like at all! Thanks.
