Hi, seven and ten are really close. Then if you want to pursue it, check around for an independent geek or computer guy or gal and then you can get them to remove most systems and then install it for you. However, be careful because they have to be SURE that your operating system is available for the change.
After talking to a tech awhile you will be able to have faith. If you want, I can give you the name of a guy in Oregon that can do it and make it work. Let me know. He is good and reasonable, so there is some postage fees but it may be worth it.
