You have the System boot files on another HD in the 100mb System REserved Partition, which can present problems down the line.

It would be best to move the System boot files into C by marking C Active, then booting the DVD or REpair CD to run Startup Repair - Run 3 Separate Times.
Partition - Mark as Active

You may need to unplug the other HD's to successfully write the System boot files to C, so that they don't interfere. Then you can delete the 100mb partition, or wipe the HD with Diskpart Clean command: Clean and Clean All with Diskpart Command

I would also use Method Two in the Mark Active tutorial to mark the data partition Inactive so it never interferes.
