My main hard drive (the one C: is on) is showing as raw

My main hard drive (the one C: is on) is showing as raw. I got a bluescreen (wish I had recorded what it said on it before I restarted, but it’s probably a moot point now) and tried to restart, but the laptop froze before Windows loaded.

I did some diagnostic stuff using a recovery drive and it became apparent that something had happened to C (it was showing as a Raw drive named D).

I reassigned the drive letters back to the correct ones but I can’t find any way of indicating that the drive is not raw. The partitions are all there according to DISKPART (Recovery 300mb, System 100mb, Reserved 128mb, Primary 237gb, Recovery 663mb), and the System partition is still formatted, as when I list the volumes, I get a FAT32 with 100MB, but everything else is raw.

Much of the drive is Bitlocker encrypted. I know there are 3rd party tools that claim to be able to recover things, but I am wary that it will render the drive inoperable, even if it will get my data back. I have most of my data backed up, I just want a functioning OS that has all of my applications.
