    Chkdsk /r /v F:-----------------------------------------------> Ok (cleaned up......unused index directories and security descriptors)
    Scannow------------------------------------------------------> Ok
    Revertpendingactions-----------------------------------> Failed (unable to access the image, error 2)
    Get-packages-----------------------------------------------> Not done
    Remove-package------------------------------------------> Not done
    Disk 3----------------------------------------------------------> BIOS/MBR

    FixMBR--------------------------------------------------------> Ok
    FixBoot--------------------------------------------------------> OK
    Scanos---------------------------------------------------------> 1
    RebuildBCD--------------------------------------------------> Failed (The requested system device cannot be found)


    What happened with the get-packages and remove-package?

    There are other commands/steps that could be tried before a reset save files equivalent, or clean install.

    1) Fix problems with RebuildBCD
    2) Fix problems with revertpendingactions
    2) Attempt Regback
    3) Macrium boot rescue


    bcdedit /export F:\BCD_backup
    F:
    cd boot
    attrib bcd -s -h -r
    ren F:\boot\bcd F:\boot\bcd.old
    bootrec /rebuildBCD
    (reboot)

    Another command option: (if you disconnect all cables or remove all drives): any of these
    bootrec /nt60 all
    bootrec /nt60 all force
    bootrec /nt60 F:
    (reboot)

    retry rebuildbcd with or without attrib

    F:
    dir
    (make sure you are able to see windows, if not seen then find the drive letter with windows)

    Regback:
    (perform dir for F: and other drive letters)
    (The proper drive will display: perflogs, program files, program files (x86), users, windows, etc.)

    cd \windows\system32\config

    (It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.)
    (All of the file sizes should be sizeable. If it displays zeros then abort.)

    MD backup

    copy *.* backup

    (It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.)

    cd regback

    (It should now display: c:\windows\system32\config\regback>)

    dir

    (It should display: default, sam, security, software, system etc
    All of these files must be sizeable. If it displays zeros then abort.)

    copy *.* ..

    (It should now display:
    DEFAULT
    Overwrite ..\default? (yes/no/all):)

    a

    (It should now display: sam, security, software, system and that the files were copied.)

    exit

    (click turn off your PC)
    (Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.)

    In windows RE type notepad > click file > search > windows\logs\dism\dism.log > copy and paste > flash drive > move drive to a working computer > upload into the thread

    Another trial and error step is automatic repair after the prior troubleshooting steps.

    This is the reset save files equivalent or custom install: (should save files, must reinstall drivers and applications)

    This is Kyhi boot rescue: (can backup files or make backup image, and test drive/hardware) (possible copy and paste folder/files from and image for a modified regback)

    First, let me say that I'm thankful for your help and time. :)
    I won't make more photos concerning the BSOD, as it's VERY tiring to edit them and reduce in size in a non-automated way.
    I did EVERYTHING you said (successful execution in console): rebuildbcd with or without attrib - yes, did your bootrec /nt + /force commands + bootsect /nt60 SYS /mbr, I managed DISM to work by booting into WinPE with BIOS, did EVERYTHING with it, pendingactions, restoreimage with source install.esd and without, removed all the packages I was allowed, tried regback but the backup folder was empty, except for two dirs with . adn .. dots, and I couldn't even TAB them to see. Also, did macrium thing - created the rescue media, loaded in it and did the fix boot issues - nada, it's a toy app.

    I'm going to do a fresh uefi install on the ssd disk, but before that I need to copy my data, if possible, transfer the whole user. Are there any automated solutions for saving user data to and restoring from custom data formats for that? Preferably with stripping the data from the old username in process. Is it too magical to exist?

    How do I do it in my situation, where I don't have the boot access to the old system? What are the best practices and software? I see you advised me Kyhi boot rescue, I will definitely use it, but are there more automated solutions also?
    Finally, what are the key things I should remember when doint a backup of my data? I know I will forget something important. I definitely wont forget to copy my chrome's profile folder, but there are other stuff to keep in mind. Help?

    But first, I want to be sure I'm forcing the UEFI mode for my drive, do I have to change any of these BIOS settings?

    The simplest way is to download and Kyhi's Rescue ISO and create a bootable flash drive as it has Macrium Reflect on it.

    See here: Windows 10 Recovery Tools - Bootable Rescue Disk from KYHI

    Use Macrium to make a backup image of your hard drive to an external USB attached hard drive is the best choice. If you don't have one, you can get a 1TB external USB drive for around $60. An alternative is to backup to a large USB flash drive. The size you need will depend on the size of your drive and how much data it has on it as Macrium will compress the data while backing it up.

    Once you reinstall Windows 10, install Macrium Reflect Free, then you can mount the backup image and copy anything you want from the image to your hard drive. The beauty of doing this is it means you don't lose or miss anything by manually selecting things to save. You get everything.

    Here is the dism.log, no last 2 days in it. But, maybe, there are some buried premises for BSOD. Uploadfiles.io - dism.log

    Thanks, Ztrucker, I have a lot of 2+ TB drives mounted. What would be the difference pragmatically between doing a sysdrive backup in Kyhi with Macrium and just drag and dropping the whole folder structure to a different drive?

    Not sure but I think a lot of the files/folders you tried to drag and drop would not copy, you would get errors and the copy would fail. Especially stuff under Appdata in your user folder. Would depend on what you were booted from to do the drag and drop.

    As I mentioned, Macrium gets everything so no chance of missing or forgetting anything you may want.

    Ok, so it's a bittersweet story: we couldn't save it, but it was reborn! Just did a fresh reinstall, thanks everyone who was helping! Say away from INACCESSIBLE_BOOT_DEVICE!

    When using copy and paste or drag and drop there can be many interrupts.
    The interrupts could be:
    a) file name too long
    b) duplicate copies
    c) etc.
    The interrupts happen in the first few hours generally.
    It could take 15 to 24 hours or more depending on the size of drive.
    On a drive problem with a 750 RPM HD there were many interrupts and it took more than 15 hours.
    The Macrium back up image was also performed.
    It was a double backup.
    Using Macrium there are no interrupts.
    The drive was not yet clean installed and the image was not yet restored.
    The plan now is to perform a custom install.
    A custom install is the reset save files equivalent.
    If the custom install works then there is no need to restore either from Macrium or from the backed up files.

    These are links on custom install using a Windows 10 iso:

    Just saw your comments on clean install.
    Hope all went well with the backup and restore.
