I have a system running Windows 10 which will not boot after reversion to previous build.

Without getting into an extended discussion around reasons for and issues with doing so, I believe it was running build 10586 and tried to update to 17134. I had some issues with this, so tried to revert back to the previous build. This seems to have failed and left the OS not booting.

The SRTTrail.txt log indicates:

Test Performed:
Name: Setup state check
Result: Completed successfully. Error code =  0x0
Time taken = 125 ms

Root cause found:
Failure while setup is in progress.

The OS SSD and a secondary data SSHD are both encrypted with Bitlocker. Whilst in the WinRE environment, the OS shows as protection paused, the data drive is locked, but can be unlocked using manage-bde -unlock -rp .....

I am in the process of downloading ISO files from MS for build 17763 and an unofficial source (I realise this is a risk) for 10586. I have another Win10 machine but that only has a copy of the original RTM build, 10240.

I'm looking to attempt a DISM repair using the 10586 ISO otherwise, does the upgrade install option when booting from the install media (intended for upgrades from Win7 etc) support an upgrade from an earlier build, if I was to us te 17763 ISO?
