i dont know how........ but some how i lost the data for the beta and i was wondering if there was any way i could get a new copy

Sure.. If you've got a subscription to Technet or MSDN. Unfortunately, the beta is no longer available to the general public otherwise. You could also ask your friends if they happen to have a copy of the ISO. Beyond that, your only other option is to wait for the Release Candidate which will be along when it's ready to be released.I wouldn't recommend trying to download Win 7 by way of torrents - you never quite know if someone's added any bonus surprises (like the ones found in those recent Mac torrents)...
