I am no expert by any means...But I think you might have to wipe your hard drive clean, create two partitions, and then only will you be able to install XP on on partition, and Linspire on the other....BTW, I just installed Ubuntu, and I love it...Ubuntu is very easy to install..similar to XP....If you have an empty partition, you should be able to load Linspire on that partition...Experts, chime in pliz !
