Two hard drives, two systems

I am running one of my machines with one 40 gb hard drive as C drive and one 80 gb drive as E drive. Is there anyway I can change back and forth and run programs from either drive other than rebooting to other drive? I am running XP Pro on both drives.

You can try manually browsing to the other drive and clicking on the programs manually...that should work for most programs.

It would be easier to reinstall the progs on the default drive and delete them from the old drive, leaving that for data storage.

Thanks, i guess that probably is my best option
