Guys,Here is my situation.I am upgrading my old Athlon XP rig which just died on me, to a new Athlon 64. I am keeping my HD, case, DVD, soundcard etc and just replacing the mobo, ram and CPU.After some research, it appears that the new system will not boot Win XP once I have replaced the above mentioned parts.My HD has two partitions (C & D) C has win XP installed on it and other non important things. D has FS9 and many payware addons installed on it. (I do have the payware backed up on cd as well)Is there anyway I can save the FS9 installation on the D drive? If I only format and install XP again on the C partition can I get Win XP to recognise the FS9 installation on the D partition in the registry?I don't want to have to reinstall FS9 and PAI, AFCAD files etc. It took forever last time I had to do this!Thanks for any advice.Glenn

You can format c: and install WinXP. After you have the updates applied, chipset, video and sound card drivers loaded, rename FS9 on D: and install a new copy to the D: drive. Afterwards rename the new one to something else, rename the old one to FS9 and you'll have the registry taken care of.The only hurdle you may encounter, is the add-ons that place key files and other anti-piracy measures into the registry and C: drive. Those can easily be reinstalled with the appropriate installation software.
