Failure to install Windows 10 April Update(version 1803)

I'm experiencing the same problem but with one slight difference. Instead of locking up on a complete black screen I get a black screen with a blue window pane logo (pain really...) At that point no rolling circles appear and the keyboard locks solid i.e. num lock stops working. I'm forced to power off. It isn't just slow as I've left it running all night on that screen.

I've escalated all the way to a level 4 tech and frankly MS debugging so far has been non existent.

They keep blaming the drivers on my system but can't point to one as a cause and I've disabled all my non-microsoft drivers before the update and it still fails. I get "0xC1900101 - 0x20017 The installation failed in the SAFE_OS phase with an error during BOOT operation".

I've done the upgrade over a dozen times six different ways with six different agents, from safe mode, disabling all drivers and the last few upgrades being directly from an ISO file. MS Support has been mostly outsource techs with scripted responses. SetupDiag was useless. There is no useful output in the logs other than logging the fact I was forced to press the power button to power the system off. My computer is healthy and passed all the various repair suggestions and corruption fixes on the MS Support site. MS insists there isn't anything wrong with the patch. Can anyone actually help me to get to the bottom of what is causing this lockup?

This is same results I get.

Can you post all your hardware for me. Just want to see what there is in common, since they claim it is a driver problem.

Can't really understand how it could be a driver problem when Build 1709 works perfectly, so the drivers are ok before.

It seems Microsoft don't even know what they have changed from 1709 to 1803, if they did this would be easy to solve!

I downloaded this troubleshooter and then ran update again and it worked.

Hope this helps

I am unable to install The Windows 10 Feature update to OS version 1803(from version 1709) on my PC.

It is giving 0xc1900101 error. I have all the latest drivers on my PC. The current OS build of my PC is 16299.371.

After each failure, the update gets downloaded again and it has failed 5 times.

I would be grateful if someone could please help.

I had an old, nursed-along Dell (I'm very mean) and a tablet both of which refused to install 1803. Plugged in a 32gB flash drive, and bingo. Installed.

Doesn't help me I am afraid. I need help to fix the DSIM problem which I believe it at the root of mt 1803 issue.
