I've done clean installs of several OSX and macOS's. Always, it involves booting up on the new OS install disk, and wiping and formatting the SSD, then installing the new OS.
I had High Sierra on my MacBook Air's SSD, and wanted to go back to Sierra.
I did the above, and now the bootable install disk doesn't detect the SSD.
I wonder if it's because the SSD is still on APFS, hence, the Sierra install disk doesn't detect it. But the thing is, I had reformatted the SSD using the Sierra Disk Tools.
