Windows 10: "Inaccessible boot device" BSOD after October update

I would consider myself a somewhat experienced PC user but don't know how to get this fixed. Hope there is an expert here who can help.

• I shut down my PC Win 10 64bit. It's a build 1809, I believe three days ago - Windows insisted on installing updates before shutdown. Fine.
• I boot the PC the next morning - doesn't work, I get the "Inaccessible boot device" BSOD.
  I learn that this is due to a mess-up in the October updates that were pushed out Microsoft's fault
• I run WinPE from the recovery USB.
  • Strangely, the repair console claims there are no restore points on the system, so I can't easily go back to a previous version.
    I know they must have been there before the update, as I created one manually just days ago.
  • I am able to uninstall the recent update through the repair options, after which the machine boots again and presents a login screen. However, I cannot actually log in no input accepted from my keyboard, for some reason and Windows forces another update whilst in the login screen.
  • Reboot - the BSOD problem is back, but now I can now no longer uninstall any updates from the WinPE repair options.
    
• The physical disks are fine. CHKDSK /f / r shows no problems. I clone my system drive to an identical disk, to have a backup. I can slave this up to another computer and access everything.
  Then I go trying to repair this mess manually. This is what I tried so far:
  
• sfc /scannow won't run out of the box, however with pending.xml temporarily removed from the WinSxS folder it runs with the offboot options and shows no problems However, I figure having to remove the xml may point to another problem
• I use dism to look at the packages that are pending: There are two Rollback packages at the end of the list In their names, one has "1.7" and the other, later "1.8"
  
• I try to remove them with dism, using the remove-package option. Fails with error code 0x800f082f.
• I investigate further and manage to find the instructions issued by Microsoft to fix the problem on the Web - a new hope:
  https://www.windowscentral.com/how-fix-update-causing-inaccessible-boot-device-error-windows-10
  I follow the instructions and find that the key to getting the faulty pending packages removed is to do a suggested registry tweak beforehand
• After implementing the fix above, I try again to remove the pending packages, starting with the most recent:
  It actually works with the 1.8 package - dism does remove the package. YES!!!
  
• I try the same with the other pending update 1.7, but it doesn't work. Fails with error code 0x800f0905.
  In the dism log, this code refers to something called "CBS_E_NO_ACTIVE_EDITION".
  
• I don't know what the error means and how to address it. Please help me out here.
  
  I am hoping there might be another registry modification that could do the trick, but I don't know which.
  I do note that while the status is "pending", the package now has an install date, which is the date when I tried to remove it.
  Resetting the system is not really an option, as I need to avoid losing all installed programs. If anyone has a suggestion to get them back from the cloned drive after a reset - that may be a viable alternative! Perhaps if I copy over certain files and folders?

Windows BSOD - Inaccessible Boot Device

Ever since December after a windows update, any time I re-boot I get a BSOD - Inaccessible Boot Device, and have to go back to a restore point. Currently my update log shows KB4054517 failed (0x80070643 on 12/12/17, Cum update on 1/5/18 filed then succeeded,
and all future updates through Cum update KB4056887 on Jan 19th succeeded. Windows runs fine with no errors, but having had to go back to a restore point 6 times in the past 6 weeks, if I reboot I will get the same BSOD and have to restore again. Any suggestions
on how to fix the inaccessible boot device error I keep getting??
