Failure to install Windows 10 April Update(version 1803)

Hi,

If someone needs troubleshooting help,

Attempt using the ISO file/Media creation tool first. If it fails,

Share Setuperr.log and Setupact.log named from 

C:$Windows.~BT\Sources\Rollback\ 

and 

C:$Windows.~BT\Sources\Panther

You can open the folder by typing the path in Run or showing hidden files and viewing through explorer.

Use Onedrive/Google Drive/Mediafire to share the files and drop the links in the next reply.

Hi,

Thank you for looking at my problem

I tried Windows media creation tool and it failed the same (about 3 times)

Strangly C:$Windows.~BT\Sources\ only contains Panther and no Rollback folder.

In panther the setuperr.log is empty

Other Actions from other threads taken so far:

*ran the troubleshooter and got:

  Potential Windows Update Database error detected Windows update components must be repaired.

* Followed the task to stop services then rename SoftwareDistibution and Catroot2 to old and restart the various services. 

* Ran Chkdsk with /Scan and then /f options. (disk errors were fixed).

* Ran DISM.exe /Online /Cleanup-image /Restorehealth

and then

* SCF/SCANNOW

Result was that SCF/SCANNOW ran clean but DISM failed with

Error: 0x800f081f The source files could not be found.

I have saved a copy of the DSIM log file.

On various threads I see different actions for 1803 update probs most of which I have now followed. But the DSIM error looks to me to be the likely cause to me. What do you think and if so how do I fix it?

Note: Each attempted retry of the update takes some hours so curently I have set metered connection.

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.

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

Hope this helps

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?
