Only OS partitions should be marked Active. Start by marking all others Inactive now: Partition - Mark as Inactive - Windows 7 Forums
If you have Win8 on one of the other HD's which we can't determine because you didn't tell us and it is not labeled, I'd boot into the Win8 disk to run Windows 8 Automatic Repair
which will at least start Win8 and may add Windows 7 to a Dual Boot menu using the Metro-style Win8 Dual Boot menu. If not you can install EasyBCD to add Windows 7 from the Win8 OS.
Or you can mark Inactive all non-OS HD's, unplug all but the Win8 HD, run Auto Repair on Win8 to start it, then after Win8 starts plug back in the other HD's to boot your choice of OS's via the BIOS Boot Menu key at boot.
