I have a Lenovo E31-70 laptop (model 80KX) that has Windows 7 preinstalled. When I tried to upgrade the system to Windows 10, the upgrade failed with the message
"We couldn't install Windows 10. We've set your PC back to the way it was right before you started installing Windows 10. 0xC1900101-0x20017. The installation failed in the SAFE_OS phase with an error during BOOT operation."
I have already installed the latest BIOS, but it didn't help.
Does anyone have some idea or some hint?
Thank you in advance.

Hi there, Jascha –
Thank you for writing in to the Lenovo Forum - happy to have you here today.
The cause for error 0xC1900101 – 0x40017 is known to be faulty drivers, however it can be difficult to identify exactly which drivers are creating the error.
Note: Please double-check the error code before reading further. There are many variations of error 0xC1900101, each with a different location code -- the error extension, located after the dash.
There have been reports of a USB driver causing this error. Until a specific USB driver can be determined as a root cause, if you receive this error, we recommend you unplug all USB devices (other than your mouse and keyboard) as a troubleshooting step and try the upgrade again. If the upgrade is then successful, you can plug the devices back in and they should function normally.
Update us how it goes.
