Changing OS between windows 7 and xp? -

I want to beta test windows 7 but i want to go back to xp once im done is can I go back to xp using only the system recovery CD?

Just install windows 7 in another partition other than the partition u used for xp. while installing dont give upgrade, just give new installation n select any other drive. or just use a virtual pc software.

Partition your hard drive, so your PC thinks there are 2 HDD s. Then install Windows 7 on the new partition. You will have a choice when your PC boots up on what OS you want to load.
