    >>>I can get to the command prompt>>>

    OK. I'm *guessing* the Win10 update somehow corrupted the SSD's bootloader. To try to repair it, google "How to repair the EFI bootloader on a GPT HDD for Windows 7, 8, 8.1 and 10" with the quotes. Click on the first link. Then click on the Win10 menuitem. Then scroll down the page to "don't have the installlation media".

    At this point, do whatever you have to do to get a command prompt. So disregard the F8 stuff. Then follow the diskpart repair directions. The only potential stumbling block is properly identifying the volume with the bootloader --- it should be only about 100MB (MB not GB). There may be two other volumes, one about 10GB and another about 20GB. Leave those two alone because one of them is how you got to the command prompt. If you have any doubts about executing any of the diskpart or bootrec commands. Stop. 

    Good luck.

    Jack,
    I'll give that ago. Once I've done all that work in the command prompt, do I just exit dos and try restarting?

    Yeah, it might do the job without having to try another ALT+F10 reset --- at least until the next Win10 update screws things up again. Jack E/NJ

    Appreciate it Jack! I'll keep you posted. Have a few irons in the fire, so it may be a little bit before I can get to it again. Certainly will update!

    Jack,
    made some progress!   Just need some fiudence when it comes to selecting the volume and assigning the letter.  

    Here’s a pic of the screen.  Looks like the drives are OK?

    Jack,
    The forum won't let me post a picture which is a bit frustrating. See if you can send me a personal message. Maybe I can post it there for sent it via e-mail?

    OK. Exit diskpart back to the command prompt. Then see if you can check C:\ for errors by entering "chkdsk c: /f" without the quotes. Let me know if chkdsk seems to be running.  Jack E/NJ

    Jack,
    "Windows has scanned the file system and found no problems. 
    No further action is required"

    At the very bottom: "Failed to transfer logged messages to the event log with status 50" 

    Let me know if you would like a pic of the results; it ran a 3 stage scan.

    OK. Looks like the hidden recovery partition was already assigned letter D. Was this the case when you first listed the volumes? Jack E/NJ

    Jack,
    Not sure. I can't recall.

    Do you recall if you tried to assign letter D to any partition? From your screenshot, it looks like you might've tried but got an invalid command message. Jack E/NJ

    OK. It might not work with its hidden status, but let's try a "chkdsk d:" without the /f parameter and without the quotes. Jack E/NJ

    Just ran the chkdsk on d ---  "Windows has scanned the file system and found no problems"

    OK. This suggests the 2nd bootloader partition (volume # 1 ESP FAT32), while appearing physically healthy, has some software issues as we originally thought. So, without further ado, we need to assign letter e: to this partition or volume # 1. So get back into diskpart. At the diskpart prompt enter the following diskpart commands---
    list vol
    sel vol1
    assign letter=e:
    list vol
    exit (if all the volumes now have a letter c: , e: & d: and everything else went OK)

    Then at the command prompt enter the following command---
    cd /d e:\EFI\Microsoft\Boot\ (if command doesn't work then try dropping the /d and enter cd e:\EFI\Microsoft\Boot\ )
    bootrec /FixBoot
    ren BCD BCD.old
    bcdboot c:\Windows /l en-us /s e: All

    Then do a cold boot. Keep your fingers crossed that it now boots back into Win10 again.

    Jack,
    Had to type "SELECT VOLUME 1" to get the selected volume correct.  Other than that, AOK with the commands. Thank you! 

    On my cold boot, I get a blue screen with the following:

     Your PC/Device needs to be repaired

    The application or operating system couldn't be loaded because a required file is missing or contains errors.

    File: \EFI\Windows\Boot\BCD

    Error code: 0xc000000f

    You'll need to use recovery tools. If you don't have any installation media {like a disc or USB device), contact your PC administrator or PC\Device Manufacturer.


    Press Esc for UEFI Firmware Settings


    It stays there for a minute or two, then goes to the Acer splash screen, then back to the blue screen with the above.

    OK. Getting close I think.  Go back to the command prompt. Then do the following---

    cd /d e:\EFI\\Windows\Boot\
    bootrec /FixBoot
    ren BCD BCD.old
    bcdboot c:\Windows /l en-us /s e: All

    Then do another cold boot to see what happens this time.

    Thank you Jack! 

    When I type that first line in command prompt, I get "The system cannot find the drive specified"

    A the command prompt, I'm at "X: \Windows\system32>

    Oddly, it's listed with no "ltr"..it's blank in the ltr column.
    Volume 0, C, Acer
    Volume 1, (blank), ESP
    Volume 2 D, Recovery

    I can send a pic if needed.

    Does the ESP still show as FAT32?
