I'm trying to make my new SSD my primary drive and my old HDD my secondary. I've tried erasing the boot sector from the HDD, but it wouldn't let me. I tried cleaning the HDD with the diskpart command and also doing a secure erase, but so far nothing has worked. I should add that I'm also trying to reinstall Windows 7. If anybody can point me in the right direction or tell me what I'm doing wrong, it'd be really helpful. Thanks.
