As a start and to rule out format errors up front, boot the Windows 7 installation media to diskpart and run the clean
command, once the clean finishes, exit diskpart and use the Windows 7 installer to create and format a single 100GB partition to do the install to.
If that does't work, after another clean
, use diskpart to create, format and mark Active
a single 100GB partition to see if that works, use Step
in the SSD/HDD tutorial for reference.
