Because the disk was made into a dynamic disk, causing the black screen cursor flashing after the boot, it seems that the partition is not found. So redo the system, but found that the disk deleted after the new. The solution is as follows:
At the point where the system prompts you not to install, hold down "SHIFT+F10" and Exhale the "cmd" command (if unresponsive, hold down "SHIFT+FN+F10" to try it)

Input: List disk, enter

Input: Create partition primary size = XXX, enter
