ThinkPad Yoga Type C020 has Windows 10 installed and won’t boot from the optical drive. I think Windows has control of my BIOS settings and won’t let go. I enter BIOS Setup and turn off Secure Boot and tell it to boot Legacy instead of UEFI but by the time it gets past POST or whatever, the BIOS settings revert back to where they were and it won’t boot from the DVD. I’ve also tried restarting from within Windows Restore Settings and telling the machine to boot to the USB drive, but no joy there, either.
I really hate Windows 10 and I want to go back to Windows 7.
