Is there a way to install windows XP on an external hard drive? I have a 1tb external hard drive, I want to install the operating system windows XP, then connect the external hard drive (with the operating system windows XP on the hard drive) to my laptop, and then choose the external hard drive as the computer boots up.
First insert the installation disk into your computer. Now instead of installing everything to your C:\ drive install it to your external hard drive. After you have done that restart your computer and you will see something at the Bottom of your screen that says something like this:
Press F2 to enter settings
Now the button might be different, for example it might say "F3 or F11". Once you've entered your settings area or also called your BIOS settings go to "System Startup Order" or something like that. Now select your external hard drive from the list and move it to the top of the list. Save your settings and exit. Now restart your computer again and you're done! Windows XP is now running completely off your external hard drive!
