What should I do if I install/upgrade the Win10 9879 preview hard drive?

First of all, please keep calm, a software-level system is almost impossible to physically damage the hard disk, so your hard disk should be no physical damage, your data still exists on the hard disk
Now understand that there are more problems are mechanical hard disk, It seems that only Chinese netizens have problems. Google, MDL, and Microsoft communities have not reported.
To solve problems better and faster, and to retain data to the greatest extent, please do not make meaningless operations on the failed hard disk, which may worsen. The worse you get, the more your data will be overwritten.
1. Try to install Intel RST driver
2. Try to restore BIOS factory settings
3. Uninstall HFS+, Macdrive and other hard disk recognition software
4 Turn off the quick start
5. Use the chameleon, Clover boot to start Win10
6. Use PE to view the hard disk, then install the low-level system
7. Turn off the UEFI (BIOS) boot
8. Skip the hard disk from Check Start
Now I have listed the following situation
1. Problems with direct upgrade installation
2. Problems with formatted installation {Formatting the hard disk with other tools} {Formatting the hard disk with the installer}
3. Hard disk failure
1> The performance of the system can not detect the hard disk, please unplug the hard disk to replace the computer, check whether it can be identified, if you can, right-click this computer - management - device manager, check whether there is a hard disk, if not, please enter the computer BIOS Check if the hard disk is detected
2>. There is no hard disk in this computer, but the device manager can detect the hard disk, but there is an unallocated partition. Please download DiskGenius to search for the missing partition table, then save and restore. >3> The performance of other computers can not identify the hard disk, there is no BIOS, please unplug the hard disk, do not operate, wait for processing
