After I pressed 'restart', and the notebook tried to boot again, suddenly the screen flashed pink-violet, then turned black. It never reached the cloudready logo for booting, just stays black, no UI. But the screen backlight turned on. The same thing keeps happening repeatedly until I am forcing it to shut down. I am able to access the BIOS. After starting it and choosing to boot off a win 10 ISO, a 'VirtualBox' screen came up. Then it switches to a black screen with a dash line on the top-left and freezes. The only way to quit it after that is to kill it through task manager. Boot, Press E, gotoline that reads linuximg - type rd.break ctrl+x, mount -o remount,rw /sysroot/ chroot /sysroot/ touch./autorelable Rebooted the machine I was able to set new root password & could login to GUI I repeated the same 2 times but 3rd time the centos on reboot gives only black screen.
