mysqld: Can’t change dir to data. Server doesn’t start

Since you used the Windows installer, everything is set up for you to run MySQL 5.7 as a Windows service, which is a great option in most cases.

Instead of running mysqld.exe from the command line,

  1. Win + R
  2. Run services.msc
  3. Right-click on MySQL57
  4. Start the service.
