I have a problem.
Recently I installed the last version of Elementary OS on my Dell Inspirion 5559 next to Windows 10.
After the installation everything was ok, I restarted my laptop a couple of times a the GRUB screen appears, so I coose Elementary and again everything was good. Once I chose Windows but later I cant never run Elementary again.
I have UEFI secure mode off but I dont know what else to do.
