mysql - mysqld: Can't change dir to data. Server doesn't start

Question

I installed a MySQL server with installer and it started. After reboot I tried to start it again and get the error:

D:Program FilesMySQLMySQL Server 5.7in>mysqld -u root -p
mysqld: Can't change dir to 'D:Program FilesMySQLMySQL Server 5.7data'     (Errcode: 2 - No such file or directory)

I tried to reinstall MySQL.
UPDATE:
When I run mysqld -u root -p as administrator, nothing happens.

Answer 1

I have met same problem. In my case I had no ..data dir in my C:mysql so I just executed mysqld --initialize command from c:mysqlin directory and I got the data directory in c:mysqldata. Afterwards I could use mysqld.exe --console command to test the server startup.
