Sooooo,
I've got a Dell Inspiron 7437 that runs EOS v6.1 just peachy.
Doing a complete disk wipe and the attempting to install EOS 7, it tells me the install failed "possibly" due to a hardware failure. Not the most helpful error statement in the world.
I've been through this numerous times, and redownloaded the ISO and made boot USB's using both Linux and Windows with the same result.
