Retrying installation worked for me. I did not make any changes in bios or elsewhere. When the errors comes up during Windows 10 installation, close the dialog boxes(do not reboot/exit installation). You will be taken back to "Install now" window, click "Install now" and proceed. You may have to try this a few times before it works, no other changes or worries required. I mostly succeed during 3rd or 4th attempt when I get the error(other times it installs with no errors or issues at all)
Did this multiple times on Lenovo Flex 2 15(more details).
