I just installed windows 10 on my macbook air. After installing it the laptop restarted and it went to a blank screen with nothing happening. I tried all the startup keys, nothing worked. I don’t know how to enter the safe mode, recovery, etc…
If you hold command-R or option-command-R while turning it on it should go into recovery mode, there’s an Apple article on getting into recovery here: https://support.apple.com/en-gb/HT201314
