    You should fix your caps-lock key before proceeding - it's broken and won't let you enter lower case letters. – a_horse_with_no_name Apr 7 at 7:26

    "UNFORTUNATELY I DO NOT HAVE RECENT BACKUP" WEll, at least learn from that lesson and start making them frequently. If you aren't/weren't prepared to lose hours/days of data, then you should have been prepared to take backups more regularly. – Larnu Apr 7 at 8:05

    Sounds like you might need urgent help from Microsoft support for this server that's long been unsuppor.... oh. – sTTu Apr 7 at 8:07

First, please don't shout.

You need to rebuild your system databases which is done using the bootstrap for SQL Server. Here is the documentation.

  • Hopefully only the model db is affected so you should save the mdf / ldf files of the other system databases before rebuilding them so as to preserve logins and the user database registrations in master db, and sql agent jobs etc in msdb – Stephen Morris - Mo64 Apr 7 at 9:40
