The one thing to try now would be unplugging the ide drive long enough to verify Windows is running good on the sata. You can also boot live with a ubuntu cd and copy+paste files and folders over to the sata and then boot with a separate GParted live cd to reformat the ide drive's primary no longer seeing Windows there.
Which version of Windows are you running there?
I did power down the PC and reboot to ensure that windows was running smoothly off the new SATA drive before powering down again to plug in the old IDE drive, if that makes a difference.
I will google ubuntu now to see what you are talking about as that is a new one to me. This seemed like such a simple solution when I first thought of it, never saw this coming. There just should be an option to turn off the IDE drive at boot in the BIOS but for the life of me I cant see it.
