It appears you had Disk 0 and Disk 1 attached when you installed. It looks like your boot partition is on disk 0 and the OS is on disk 1. The 415Gb unalocated on disk 2, right click it and select create simple partition and when finished with the wizzard, you will be able to see it. To fix it, I would disconnect all disks except Disk !, run diskpart from the installation DVD and mark the C partition active. Then Run Startup repair at least 3 times with reboots in between, or until it starts. Then reconnect the other drives and mark Disk 0 inactive.
