Did it refuse to install, or refuse to boot? I've seen Linux distros that couldn't boot (from CD), but it worked after disabling certain hardware detection in the boot options.
Starts to boot from USB drive, and than just halts and does nothing, just showing blank screen.
I know how to handle bios and boot options, but this was not the case here and usb was detected.
I don't have much experience with OpenSUSE, but sometimes it's because secure boot. You might want to disable it during installation and optionally manually sign the boot loader later with this
