Windows 10: Inaccessible boot device

Suddenly, I cannot boot my Windows 10 Pro (v1903).
I was fine with the new upgrade to version 1903 for a couple of weeks but for reasons I cannot determine, I am now getting the error message: INACCESSIBLE BOOT DEVICE.
I got into the repair menu and through DOS I issued a bootrec.exe /fixboot command but received an ACCESS IS DENIED error message.
I used my one and only restore point and was able to get back up. But when I rebooted the same INACCESSIBLE BOOT DEVICE message reappeared and now I have no restore points to work with (so a lesson to you all: check whether Windows is creating more than one!).

Also, I tried the usual chkdsk & sfc commands which (as usual) were useless.

Thanks in advance for any suggestions.

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.
