Downoad the Hardware Maintenance Manual for your system. Look for a section titled: Recovering from a POST/BIOS update failure.

For reference, here is the HMM: https://download.lenovo.com/pccbbs/thinkcentre_pdf/m83m93p_hmm.pdf
Manual page 290 details the process that BiggAl mentions.
Hope this helps.

Similar situation solved by Boot block Recovery:
