In Disk Management, right-click the disk marked Missing. Click Reactivate Disk.

Why do you have Dynamic disks, which are meant to span a data partition across multiple disks?

If Win7 will not boot you can try to convert it to Basic using one of the non-destructive methods in Convert a Dynamic Disk to a Basic Disk.

The method I use is here to convert dynamic disk to basic disk with Partition Wizard bootable CD. The last version this feature was free in is ISO - Windows Live. Download and burn ISO to CD using WIndows Image Burner, boot and follow the tutorial above.

C is now missing both the System and Active flags so it may be necessary to Mark Partition Active and run Startup Repair - Run up to 3 Separate Times to see if Win7 will start.
