I have this same problem since yesterday.. after the recent update I cannot boot my laptop. Lenovo Z400

It loads auto repair ..then on to diagnosing your comp. It will be stuck there..forever.

Tried so many tips and solution from internet and no resolution. Included USB boot disk. KNN Win 10 cannot safe boot...

Tried to reinstall - Also cannot says drive is GTP.

Any ideas huh? If no solution, looks like have to send to IT people le..but i need the laptop for work ...screw you MS for forced updates.

oh the error i got was : bad sys config info at the BSOD
