I find it very useful to have a USB 3.0 flash drive with Debian installed on it. Get a good USB 3.0 flash drive, 16 GB or larger, and try installing Debian onto it. Make sure the installer sees the target drive as /dev/sda.
Use another computer if you choose this option.Have you tried resetting the CMOS settings to defaults? Is there a motherboard jumper for resetting CMOS settings? Be sure to write down or photograph the current settings before you do either of these -- Windows 10 may not boot for certain setting values.
