If your BIOS allows selection of the external device in the boot sequence, you should be able to do this but installing XP on such might be tricky as you may need to preload drivers and such. An easier way, if you have an unused HD bay in the PC, is just to install another hard drive and install XP on that. This way you can select the ME or XP drive by entering the BIOS when you start it up. You could use your external just for storage. You will need to make sure your PS has a bit of reserve to accept another device. Anyway, that's how I would do this.
Hope this is an OK place for this topic.
I'm running a Dell Inspiron 8000 with windows ME. I'd like to keep ME running so I can hang onto some of my older programs. However, I'd also like to have XP so I can run some more current stuff.
My internal Hard Drive isn't big enough to accomodate both operating systems, but I have a huge external firewire drive. I'm wondering if it would be possible to install XP and the XP programs on that external drive and set up some kind of boot selection process.
any help is greatly appreciated.
