I try to install tumbleweed (No windows) on my new laptop . install using external dvd-rom (usb) .

whether secure boot is enable or disable , installation no problem . but getting problem when boot

if secure boot is enable
able to boot to grub screen , select any of the 2 options , after loading ramdisk ,will get blank screen

if secure boot is disable
able to boot to grub screen , sometime only (advanced option) able to boot to login , sometime blank screen
after restart using ( shutdown -r now) , select any of both option in grub will go blank screen

Help
is there a way to boot with secure boot enable?

there problem with shutdown.

i shutdown by calling “shutdown now”

sometime shutdown , some time restart.

Apparently you have a Skylake processor (i7 6500U ?).
Please see if this thread is of any help
