I have a 500 GB Laptop drive that no longer boots

This is the first time using Testdisk. The system know the drive is there but says no operating system is found. I ran testdisk and it found 3 partitions, here is the information from the log file. the computer I am running Testdisk on it a Windows 7 OS with the bad drive running Windows 8. The drive is a Toshiba MQ01ABD050, 500 GB 16383 Cly, 16 Heads, 16383 Sectors (LBA 976, 773, 168 Sectors). What would be the best way forward?

After Analyse, choose Quick Search, try to list the content of each partition (key P).
If some partitions are still missing, choose Deeper Search and try again to list the files

When I slave the drive into another computer I see 2 partitions, the C drive and the recovery drive. I see the folders but they are empty and C shows 99.2 GB free of 99.9 GB and D shows 3.26 GB free of 27.8, but the drive is 500 GB.
