Problems with bit locker

[sgmidf]

I have an x220 running W7 enterprise on the 320 main drive. I was happily working and got an "I/o" error message and the machine shut down. When I reboot it give me a bit locker error saying that the boot info has changed and to supply the key. I do that and it goes to repair or start normally. If I select repair,it says it's loading files and goes nowhere. If I select restart it flashes then goes to a BSOD and recycles.
I'm I completely hosed here? I've also got LoJack on the box.
Any help would be greatly appreciated

Run the HDD diagnostic program in the BIOS. It doesn't sound like a Bitlocker issue to me.
