I am new to the Linux world so please bear with me if I don't know anything common.
That being said I tried to install elementary OS Juno releas-juno yesterday and when I booted from my flash drive it stuck at the glowing boot logo. I pressed ESC and it said
failed to start light display manager. If its relevant I already have Windows installed and wanted to dual boot it.
I also have
failed to start network manager and
failed to start detect available gpus and deal with any system changes
The problem was in the flash drive. Used a new one and it worked like a charm. So if any one faced this problem try to change the boot device or use a dvd. It might work.
