I tried to install Fedora 23 on dual-boot with an USB stick today. I followed this video tutorial: https://www.youtube.com/watch?v=gOP_FtP1e9U
I'm in UEFI mode, so I installed Fedora and everything worked perfectly until I had to reboot, then I got this error:
Reboot and Select proper Boot device or insert Boot Media in selected Boot Device and press a key.
I searched a lot for this error and it seems that a lot of people have problems with it. So I tried to resolve it by restarting my computer, going into the BIOS settings and changing the order of my boot device so my hard disk was in first place and my CD/DVD was in second place, I saved and restarted, it didn't work.
I also tried to put the CD/DVD in first place and it didn't work either, my BIOS version is 2.15.1227. I can only put my USB stick back and load fedora in live mode, so I tested the command to see in which mode I am and I am still in UEFI.
Here is my boot order:
I disabled the secure boot and the hibernation mode is on.
Even after changing the boot order, I still get the error; I don't know what to do.
