I have a Acer Z3-715, 1 year and 1 month. When it was updating to Windows 10 1903 it got some errors. I tried the recovery but after the recovery it was very slow. So I decided to do a Clean install, and then I got the problem.
I followed the instructions on Microsoft official website, use the Microsoft official tool, create the USB installation Media from another Windows 10 machine I have. I ran the installer on the new machine and everything appears to go well up until it's time to restart. When the machine restarts, I get this message:
Your PC/Device needs to be repaired.
The operating system couldn't be loaded because the system registry file is missing or contains errors.
File: \\Windows\system32\config\system
Error code: 0xc0000185
There were some occasions of getting this error when a restart gave me a slightly different error: a BCD error.
I searched on the internet and so far I found two exactly same case as mine.
On the post in Microsoft community below it seems the problem was resolved by restart the working PC before using it to create the installation media. it doesn't work for me. I even tried using DVD to install but still get the same problem. I doubt there would be some other actions which fixed his problem such as replacing HDD.
Clean Install Troubles; Error code: 0xc0000185
On the Post in Acer community below, the problem is not fixed and no further update from the poster.
Cannot get Z3-615 to boot from USB or CD/DVD with Windows 10
I tried a lot of ways but none of them work. The last thing I want to try is replacing the HDD. but I want to get some other proposals before trying that. I did run chkdsk and proved my HDD has no error.
Here I list all the way I tried. It is a very weird problem. How come a Clean install could get such problem? Hope someone could help find the root cause. it is also a good opportunity to learn and share. Thank you very much.
1) Restart working PC then use it re-create the install USB media with Microsoft official tool--------same result
2) Download ISO from Microsoft official site, Burn to DVD and use it to install--------same result
3) Download Windows 10 1803 ISO by Rufus, use Rufus to create Installation Media USB--------same result
4) Download Windows 10 1803 ISO by Rufus, Burn to DVD and use it to install--------same result
5) Try different USB drives to create the installer, then re-install--------same result
6) Running Automatic Repair---------it shows diagnosing, then eventually shows something like problem cannot be fixed.
7) System Restore / System Image recovery --------cannot do it. since this is a Clean install.
8) Before installation, Shift + F10 to open a Command Prompt, type the following commands followed by Enter key: DISKPART, LIST DISK, SEL DIS # (replace # with the disk # of the Windows disk from list in previous command) , CLEAN, EXIT. Then install--------same result
9) Disable Secure boot in BIOS, then boot from installation DVD to re-install--------same result
10) Reset BIOS to default setup, then boot from installation DVD to re-install--------same result
11) In the Command Prompt, run Chkdsk C: /f /r. it completed and no error found, re-install--------same result
12) In the Command Prompt, Run command bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd, -------after last command, it shows "Total identified Windows installations: 0"
13) Use AOMEI Partition Assistant Professional to Rebuild MBR, then re-install--------same result
14) Disconnect all peripherals (keyboard, mouse), re-install --------same result
