Did you wipe the HD before trying install? SSD / HDD : Optimize for Windows Reinstallation
The boot sector may be corrupt and need wiping.
Where did you get Windows 7? Verify the ISO integrity and burn another DVD using ImgBurn at 4x speed, or write the ISO to flash using UltraISO trial version: on File Open ISO, on Bootable Write Disk Image, Format, Write.
You should be able to see the two partitions created during install. A 100mb System Reserved boot partition is created to be System Active, then a Windows 7 partition. After install only Windows 7 will be lettered C regardless of what WinRe or Diskpart tells you during install; I'd stop mucking in the bcdedit as everything related to that is automated during install, and also now automated in Startup Repair.
