The issue was with PCR5.  For ThinkPad T470, the BIOS that fixes this issue will be version 1.40 that is scheduled to be released later this month.

Hi All,

 

I also have windows 7 with legacy boot and 1.2 TPM.

In my case disabling the thunderbolt port in Bios settings did the trick.

I've restarted the laptop several times and bitlocker error message didn't show up.

 

 

Greetings

This is the first time I've ever heard of someone disabling Thunderbolt to get BitLocker to work.  What's your Boot Order look like?  For Win7/legacy, the HDD must be first, and there can't be any entry like "Windows Boot Manager".  Otherwise, BitLocker will have problems.
