Acer Aspire F15, dual boot Windows 10 and Ubuntu 16.04 LTS, NVIDIA, UEFI, Secure boot. Installed openSUSE Leap 42.1 successfully in virtualbox machine on Ubuntu. When trying to install same image from USB on the laptop to replace Ubuntu, it boots and after the initial and slighty simpler boot screen (which is correct on UEFI machines), I get a screen with three grreen bars at the bottom, but then Iḿ presented with a >>> linuxrc 5.0.61 (kernel 4.1.12-1-default) <<< screen. In a box I can select an installation medium. My installation medium is USB. However, this is not offered as a medium in the box. It only shows "cd: / , hd: / , http://download.opensuse.org/distribution/leap/42.1/repositories/ ".
None of these options takes me any further in the installation process. Any suggestions are welcome.
