Windows 10: Unable to Upgrade from Win10 1909 to Win10 20H2 Error Code 0xC1900101-0x20017

I am currently running Win10 Pro Version 1909 OS Build 18363.1440 and trying to upgrade to Win10 20H2 before the EOL for 1909 in a couple months. I keep getting an error code of 0xC1900101. I have been doing some research on this error and I have already done the following:


Updated drivers including display and network drivers

chkdsk /f

sfc /scannow

DISM /Online /Cleanup-Image /Restorehealth

Disabled VM in BIOS

Clean Boot

Tried installing Win10 2004 instead also failed with same error


Yet, I still get the same error every time. It gets to the restart after installing 20H2, then just after the Windows logo appears, it restarts again a couple seconds later, then it loads back up still on 1909. It appears to be trying to boot 20H2 after the first reboot, then fails, then reboots again and rolls back to 1909 when I tried installing from the 2004 .iso, in addition to getting the full error code of 0xC1900101-0x20017, I also got the "Installation failed during SAFE-OS phase with an error during BOOT operation" error after it rebooted.


My hardware is as follows:


Motherboard: AX370-Gaming 5

CPU: AMD Ryzen 5 1600X Six-Core Processor 3.6 GHz

RAM: 16 GB

Video Card: NVIDIA GeForce 1060 6GB

Primary Drive: 240 GB SSD 35 GB free

Secondary Drive: 1 TB HDD

I also have a printer connected, but it is not turned on


My antivirus is Windows Defender no third-party AV installed

Any help would be greatly appreciated.

Thanks!

Hi Antony,

As i am getting error code 0xC1900101 - 0x20017 but you suggested to refer 0xc1900101-0x40017. Just asking which one is right solution for my
issue ?

I have already tried the steps mentioned for error code 0xC1900101 - 0x20017 but No luck.

I also tried to upgrade through Windows Update but same error.

Thanks

 

Can't upgrade from Win 10 Pro 1909 0xC1900101-0x20017

For months Windows Update has offered to install 2004 and then 20H2 but the install always fails after the first reboot and rolls back to 1909. I've tried reinstalling 1909 on top of itself from an ISO first and then upgrading, running the update from a 20H2 ISO file and even doing a clean boot before trying the upgrade from an ISO. All fail with the same error code:





Can anyone offer advice on how to resolve this?

Thanks!
