Krimpr, I think what your doing with a removable drive will work. Essentially, what you're saying is that you will have your entire computer boot on one drive or the other, not a hot swap arrangement. I think you're saying both drives will be primary active partitions and its one or the other, never both. Oddly enough, I don't have these kinds of problems with P5. I posted the thread because I had similar problems on winME some months ago. If anyone should have problems, it would be me because I have ME and 2k loaded in dual boot configuration both on the same partition but different directories. They share IE6 and they share all my programs. If I load Photoshop in a directory called PS55 for win ME, I then see if it runs in 2k off that same directory or if it has to be reloaded. If it has to be reloaded, I reload to the same directory and overwrite the program. This saves a lot of disk space. Say it can't be done, but I'm on a rock solid stable machine. Though getting there was a heartache after realizing that dll's were getting overwritten and had to be replaced. That's why I suggested rerunning win setup from the windows run box or from the CD while still in windows. It will keep your registry and reload some of the dll's that Roxio etc, changed. It was the only way I could stop the blue screens even after uninstalling roxio.
