I have a 300GB external hard drive. Recently, I copied Vista installation files to it and was able to successfully boot it up and install the O/S with no problems. Now, I'd also like to add the XP installation to the external HDD and I know I can only put one of each. If i were to separate each installation with a folder, would i be able to create a boot file that would allow me to choose between each installation right after the POST? Much appreciated folks
