Acer TC-780 SSD stops loading in BIOS after recent (Aug-Oct 2020) Windows 10 update

After each of the last two windows updates, booting my TC-780 gives the "Reboot and Select proper Boot Device" error because the SSD drive with the Win 10 OS is no longer being recognized by the BIOS.  Only the second 1-TB HDD drive is being recognized.  Each time, loading Win10 with a recovery USB stick and restoring the OS on the SDD to a pre-update restore point allows the BIOS to recognize the SSD and boot normally.   It runs fine for weeks until the next Win10 update, then it goes back to not booting.   I have verified this is the issue twice by getting it to work again after restoring and removing the offending Win 10 update.   I then re-applied the latest update again and now it is not booting again.  This is the current state of my computer.

What can I update or do to keep Windows updates from killing my SDD at boot?  I checked the ACER driver site for any BIOS updates that might address this, but didn't see anything that seemed applicable.   This has only been a problem with the last two Win 10 updates in the last 2 months.  Every other Win 10 update prior had no issues. 

Relevant info:

Model: AT6W1
Bios Version :  R02-A3
Build Date : 5/26/2017

    Do you have two boot drives ( the HDD and SSD) connected to the PC at the same time?

    No.  The HDD is not a boot drive.  No OS.  It barely has anything on it at all.  Also, I have attempted to boot with the HDD SATA cable removed when I was trying to diagnose the issue before I figured out it was the Win 10 update.  It doesn't change any behavior to have the HDD disconnected.

    Have you tried to reset BIOS to the factory default after having problems?

    Yes, several times.

    I updated Windows 10 a few days ago.  Since then, when I boot I get stuck in a loop.  Sometimes it says "automatic repair", sometimes it doesn't.

    Then I'll say that is Widows 10 software problem. Hope Microsoft will solve the problem with the future updates.

    Sometimes unexplainable problems can be solved with BIOS update.

    Is there an overall BIOS update I should be using?  On Acer's product support page for the TC-780 under BIOS there are what look like specific fixes to specific problems, but no overall upgraded BIOS to flash.  https://www.acer.com/ac/en/US/content/support-product/6817?b=1

    Never mind.  After looking closer I realize that each of those is a full BIOS update, and the descriptions are just the main issue that update addresses.  I will update to the latest version and see if that works.  Thanks.

    So I updated the BIOS, restored windows 10 to a pre-update state and it booted up.  I updated Windows 10 with all available updates, and it still appeared to boot up fine.   However, when my in-laws got it home, the next day it went back to not recognizing the SSD OS drive at boot.  So, I am at a loss as to what to do next.

    It's sounding to me like the issue is more likely hardware with the SSD than the software directions you have been looking. Which drive is installed?

    I'll take it out and look, but it is the stock m2 ssd that came with this:  https://www.newegg.com/acer-tc-780-neselecti5-student-home-office/p/N82E16883101369

    It looks like they used both Lite-On and Toshiba drives in the 256GB versions. Use one of the SMART disk utilities to see if there are any errors being recorded.

    The key SMART stats that I look at are:
    Attribute
    Description
    SMART 5
    Reallocated Sectors Count
    SMART 187
    Reported Uncorrectable Errors
    SMART 188
    Command Timeout
    SMART 197
    Current Pending Sector Count
    SMART 198
    Uncorrectable Sector Count
    Yours are pretty high, especially 187, and I'd expect from that info that the drive is going to finish failing relatively soon... :( Get a replacement and clone before that happens, but do some backing up even sooner.
