hi liu,

 

this error can happen due recent hardware or software change. based on post, tried resolve issue going through pc’s command prompt yet you’re still getting issue. have tried boot usb device media creation tool? if not, we suggest follow instructions given jkwgoo , srimadhwa b on this article. on steps provided on said thread, may asked repeat steps such fixmbr , other steps did. difference time, have windows 10 media creation tool boot pc.

 

let know if resolves issue you.
