Hello, my machine is Lenovo P50 laptop. I’m using Fedora 26 as a Linux distribution (it is the first OS in the GRUB menu) and Windows 10 (as the next choice in the GRUB menu). I used such configuration for a long time but since yesterday, out of nowhere, when I press the power button on my laptop, the main logo of Lenovo and GRUB menu does not appear. The screen is black, turned off, until fedora is loaded (it is first choice in Grub menu and it is chosen automatically after 5 second I think). Fedora operating system works correctly. Moreover If I turn on laptop and hold down “Down Arrow” for 10 seconds and then press enter, then Windows 10 LOADS and I can see the Windows Lock screen and can log into the system. But let me stress that the screen appears to be OFF unitil Lock screen is shown.
Unfortunately for me, I tried to do fix this on my own and in Windows I used msconfig and set the Safe Mode option. Then I restarted laptop but now the screen is black constantly. The only thing I can now do, is to power my laptop and wait until Fedora 26 loads. If I do the trick with Down Arrow, Windows probably loads but the screen is black.
So my questons are as follows:
Can I from Fedora OS disable the Safe Mode for Windows ?
Can I use some commands in Fedora terminal to diagnose or bring back GRUB menu after laptop is powered on ?
Let me also add that connecting additional monitor does not work…
Please give me some hint how to get out of this madness.
