What should I do if I can't find the hard disk when the USB disk installation system starts?

First of all, the compatibility problem of the USB disk boot disk itself should be ruled out. You can use the U disk boot disk making tool to remake it, because the deep USB disk is very compatible at present.

Check the USB disk production tool: Make sure that the USB disk production tool used is compatible with the hard disk model and interface.
