We have a remote user that we discovered does not have bitlocker enabled. She does appear to have a partitioned logical drive(f) called HP_TOOLS. Our main concern is to bitlocker protect the C drive. The machine is a HP ZBook 15 G3 laptop. we do not image our machines, and in searching for this error, I'm not finding any recent resolutions that fit for Windows 10. This user could possibly bring her laptop in, she is about to be on leave for a while and says she might be able to bring her machine in. I'm open to listen to any/all suggestions about this.

    Make sure her disk doesn’t have any unallocated partition. Then refer to this link for solution
