    and run the chkdsk
    Done. Windows made corrections to the file system, but after rebooting, still "No bootable devices found".

    How would I perform an in-place upgrade when I can't boot to Windows?

    He cannot boot into windows
    You will only be able to do a repair install of Windows 10 from within Windows 10.

    devnull

    I know you have checked that windows boot manager is the boot device
    please go back to UEFI setup and check that the drive is shown in the setup, NOT the boot part of the setup, but the item that shows the drives recognised by the firmware also check please what mode is shown for the drive
    eg. AHCI.

    Providing everything seems Ok there
    could you go back please to cmd prompt
    type
    bcdedit
    and as you will be in recovery mode, could you record the bcdedit as a camera shot and then attach it please.
    OR if you know what you are looking at check it is OK
    Basically you will have a windows boot manager and then a windows boot loader as on this link
    https://docs.microsoft.com/en-us/win...tings-for-uefi
    the other mentioned diskpart etc are not applicable at this stage.
    You are only using that example on the link to check the bcdedit.
    Here is another example
    =======================================
    Your data should be OK, when you try the next step, but what please do you need to keep from the Inspiron, just in case, something goes wrong.

    There are a few ways to do this - to copy your data
    Do you have an external hard drive you can connect to the Inspiron

    I do not wish to be confrontational - that is not my style
    but to post a repair install when it is obvious the system cannot be booted into windows and then when that is pointed out to you - to post
    If all else fails, do a Clean Install
    is NOT a great deal of help.
    ===========================
    nevertheless - thank you for posting.


    -----------------------------------------------------------

    We are not even close to a clean install - please do NOT consider it at this stage.

    10-4 on that. ;^) I've been doing this sort of thing for way to long to have that thought even cross my mind at this point.

    The SATA drive is shown, configured for AHCI mode.

    Providing everything seems Ok there
    could you go back please to cmd prompt
    type
    bcdedit
    Got the following message: "The boot configuration data store could not be opened. The system cannot find the file specified." So.......?

    cheers
    I suspect we will have to rebuild the bcd
    Before we proceed
    what please do you need to keep from the Inspiron, just in case, something goes wrong.
    I do expect anything to go wrong, but it is a wise precaution to back up at least your personal data just in case

    OK
    follow this procedure please
    https://www.dell.com/support/kbdoc/e...ur-dell-pc#GPT

    UEFI
    so in the recovery cmd prompt
    type
    diskpart
    then
    type
    list disk
    you should on that inspiron only have the one internal drive listed - I think

    The output will show you that the disk with windows is GPT by way of an asterisk

    When you have identified the disk select it
    select disk 0
    in diskpart disks are numbered at that stage - not lettered
    it will respond
    disk 0 is now the selected disk
    now type
    list volume
    you should see the EFI partition which should be FAT
    you should also see the windows partition - which of course will be NTFS
    and a reserved partition and probably a recovery partition.

    Then go from the guide on the link above by lettering the FAT partition, as that is the one that in the boot order is named
    windows boot manager and is the partition form which windows first boots - as you can see on my screenshot on post 14.

    You need to letter it, so that you can then write the new bcd

    Here is another guide for you to also look at although it is the same as the one from Dell
    How to Repair EFI/GPT Bootloader on Windows 10? | Windows OS Hub).

    which also shows the first part of my typed cmds.

    Cheers
    One point I forgot to explain if necessary is that the cmd on the dell link
    bcdboot c:\Windows /l en-us /s <boot letter>: All

    does not make it clear which is boot letter
    it is explained on the other link
    bcdboot C:\Windows /l en-us /s k: /f ALL

    where k: is the letter that was allocated to the FAT partition


    I will wait to hear from you
    Even if it does NOT work, we still have options left before you have to resort to a reset/refresh
    OR at worst a clean install
