Can I Dual Boot Xp And With Windows 7 From My External Hard Drive?
I have only 10gb of space left on my laptops hard drive with XP on it. Can I install Windows 7 on my external hard drive, and dualboot that way?
My external hard drive also has files on it so I’d rather it not be formatted by installing Windows 7 on it, if that’s possible?
Thanks!

Here is a guide to booting Windows 7 from an external HDD: http://www.istartedsomething.com/2008110…
I cannot vouch for the guide’s validity because it is not a Microsoft site, but based on the comments it looks like it works.
