Today i started up my computer normally and got black screen which said "reboot and select proper boot device". I went to my computers bios and i changed some settings (i am noob) like i enabled "fast boot" and booting order and i restarted my computer and got only black screen after that. Later i found out that only 1 plug was off my SSD and thats why it didnt boot earlier. Now because i changed the settings from BIOS i only get the black screen and i cannot access BIOS anymore. Any help how to solve this? Thanks and sorry for my bad english!
