How exactly did you wipe the HD before the last install?
You said you used the same ISO to install before - was that during these attempts or on another computer that is running Windows 7 fine?
I would install HashTab to check the HASH
of the ISO against official Windows 7 HASH: Windows 7 RTM SHA-1 hash / checksums
as your ISO may be faulty depending upon where you got it.
Then burn another DVD using ImgBurn at 4x speed.
You seem to want to focus on repairing the failed install while we are still waiting for answers to confirm you even have a reparable install. Please answer questions in depth to get further help, not just "I tried all that."
