It should be RC3, and I do not have a 1TB drive. My collective hard drive space is approx 700. I have had trouble installing bootloaders recently. The RC2 installed pkg fails, manual installation doesn't seem to want to happen either. But using a packaged version of the RC3 it looks like I was able to at least get the bootloader to start again, but it KPs just like before.

Edit: I think I need to start fresh with the bootloader situation entirely. I don't really know how to do that, the most I have been able to find regarding uninstalling a bootloader is to simply install a new one on top of it. But that makes me nervous.
