Try enabling "legacy boot" in BIOS?

Edit: Should be under boot options.

It is not that it is "harder" to install your own OS, you just need to disable Secure Boot and enable Legacy booting in the BIOS. Secure Boot lets Windows control the boot process and not allow any unsigned processes from loading during boot. It actually stops a lot of attacks and malware.

On any OEM based laptop/desktop Secure Boot will be enabled which has Windows take over the boot management. If you reboot into the BIOS it will show a "Windows Boot Manager" as the only boot option so long as Secure Boot is enabled. If you disable it you can activate UEFI and Legacy boot options so you can boot to both.

There should never had an issue booting original install media for 8 or above via USB flash or DVD with secure boot enabled (the boot menu should show a UEFI boot option for either).
