Set Disk0 first to boot in BIOS setup.
If it still doesnt start unplug Disk 1 and run Startup Repair - Run up to 3 Separate Times.
When Disk0 boots you can plug back in Disk1 making sure it is not set to boot first again.
There are no user files on Disk1. As you can see your OS partition is Unallocated meaning it has been deleted.
You can undelete partitions which have not been overwritten using Partition Wizard Partition Recovery Wizard - Video Help.
Then you should be able to browse in from Windows 7 to copy over your files to DIsk0, wipe Disk1 using Diskpart Clean Command
to repartition in Disk Mgmt.
