I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101.

The installation starts, and after a couple restarts, it says:

" Attempting to recover installation "

" Undoing changes made to your computer "

And then I am greeted with error 0xc1900101 on Windows Update.

    I've solved it! I have two SSDs on my PC, and I remove the after one（Toshiba 512G）, and it works! If you have two SSDs too you can try it

    I have the same question, I tried to upgrade to windows 11 via dev branch of the insider program, and after it downloaded and installed the upgrade, it just rebooted and stopped doing everything at the computer's logo page, I had to press my power to shut it down and tried to boot again, it booted normally but didn't upgrade to 11 with a code 0xc19001010
