Win10 upgrade, there is 0x80070002 error prompt how to do?

The first situation: may be caused by the addition of other drivers in the system, we have encountered in the previous examples, before the win10 computer used HDD mechanical hard disk as the main hard disk, and later joined and enabled the second hard disk Such as the SSD solid state drive as the main hard drive, this may happen. The solution is to back up the hard disk information and then format the hard disk of other partitions.
The second case: It may be because there is project interference in the service options of the Windows system. We can open the run window of the win10 system, then enter msconfig and click Enter. In the open window, we will switch the interface to the service column, then click on the bottom left corner to hide all Microsoft services. It is enough to disable all the services that still exist.
