Hi,
See a related thread here: http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-and-Recovery/Invalid-Feature-Byte-CRC-fail/td...
Your model BIOS simulator is here: https://h20464.www2.hp.com/results.htm?SID=7815294&MEID=2861D288-64A0-4403-9BC8-D8EBC07E9965
If that's not resolving this issue, kindly contact HP technical support directly.
