Ok,it's fixed now, here is what works for me

Boot up your PC and wait until it fully loads to the windows 10 start menu.
- Hold down the power button and wait until the computer fully turns off.
- Quickly move to the back of the computer and unplug / replug the power cord.
- Press the power button, and as quickly as you can move to hold the DELETE key.
- Windows 10 will boot saying "Please wait" instead of normal booting this time.
- When it boots, you will be presented with options which will take you to the ability

网上找到的法子，极器“想“（响）了好一会，“please wait”之后，把鼠标直接还给我用了。不需要option什么的。
