Windows 2019 in place upgrade from Windows Server 2012R2 to 2019 VM keeps popping the same error 0xC1900101 - 0x20017

Question

So Im doing an in place upgrade from Windows 2012 R2 to Windows 2019 and I usually succeed in some of the machines I upgrade, this machine keeps pulling out the same error ID.

'We couldn't install Windows server 2019'

0xC1900101 - 0x20017

The installation failed in the SAFE_OS phase with an error during BOOT operation

• I googled the results and just went through a number of possible fixes, uninstalled the VMWARE display adapter, made sure the drives are all scanned and clear, increased the ram, made sure the CPU was only 1 core and etc. Still the same result.
• Is there something in the Setupact.txt file I can find that might point me to the right direction?

Answer 1

Hello,

Firstly, I suggest that check for update, if any security update could be found, installing them to update the system to latest version. Then perform a clean boot. After that perform an In-place upgrade again.

How to perform a clean boot in Windows - Microsoft Support

If the issue still insists, go to %windir%\Panther directory, and then locate the Setuperr.log and Setupact.log files and open them. Among the two files, Setupact.log is specifically created when an upgrade fails. You will have to look for a reference for failure in the log file and find the driver responsible.
