So I added this option when starting mysql:
bin\mysqld-nt --skip-grant-tablesThis forced it to start even without grant tables. Now, the grant tables still must be created, and after browsing for a while I found out that we could initialize the grant tables using these scripts:
The first run spits errors. Seems that I must manually do these before those scripts:
create database mysql;Then I retried running mysql_system_tables, then all the other scripts. After restarting the mysql server, all seems to be working correctly.
