Start up disk
I was trying to do a factory reset of my Macbook Air (2017) last night - I was able to erase (not delete...I was never given that option, so as far as I know I didn't actually delete anything) my startup disk and get to the point of reinstalling macOS (High Sierra), but when it asks me what disk I want to install it to....there's nothing for me to choose. Any ideas/suggestions on what happened or what my next move needs to be?! Thank you!
MacBook Air 13″, macOS 11.1
