Just build the new development server and installed couple of instances with SQL 2008. Restart the Server after installing SQL2000BC and SQL200DTC, now getting error saying Device Not Ready and SQL not starting.
Without more information, it's hard to say, but the most frequent errors are security related. Check all the services and the accounts they're using. The second most frequent error is network related. Do you have the write protocols enabled? The third most frequent error is path related. Do you have all the right data drives, etc.
AFter that, you have to be driven by the error message.
