Its booting off the System REserved partition on the other HD, which is not correct and needs to be changed.
Mark C Active in Disk Mgmt, power down to unplug DIsk1, boot into BIOS setup to set C as first HD to boot in BIOS setup, boot into Windows 7 installer to run Startup Repair up to 3 separate times with reboots - until C is labeled System Active.
You can plug back in the HD then and delete System Reserved and the old Windows 7 partition, or wipe the HD to get it cleanest with Diskpart Clean Command.
All of this was unnecessary waste of time because you wouldn't read the steps given you. Why?
