Brand new build all new parts. I recently installed win 7 ultimate. Created a user name and password went to register and realized my key is for pro. So I download pro from ssme site set it up to boot from USB like before. It goes to install I format HDD and 5% into Windows expanding I get error 0x80070570. I tried removing battery from mobo to reset. Tried doing install again after error. All my hardware just worked installing ultimate and now I'm getting this error?? Do I need to wipe my HDD and try? I don't get it?
