If you can transfer all that data to the Sata drive, set up the sata and install windows: put the ide drive in as the slave; transfer your data to the sata. Then set the sata as the slave and install windows on the IDE master. You now trnasfer your data back to the ide drive and keep the sata as a slave or (better for speed) once you have transfer your data to the new sata keep it as the boot master and use the IDE as the slave for back up with all your data already on board!!!!! Better to have two hard drives for back up anyway!!! Capice? (italian for "Understand?")
