debian server not booting

I am looking for a freelancer who can help me with my Debian server that is not booting. I am receiving an error message when trying to boot the server. Software diagnosis: The server gets stuck during the boot phase with the message: (emergency mode). The same behavior persists on subsequent boots, so it has been rebooted on Rescue mode.

Requirements:
- Experience with troubleshooting and diagnosing issues with Linux server OS
- Knowledge of Debian server configuration and maintenance
- Ability to identify and resolve booting issues on Linux servers

Responsibilities:
- Identify the cause of the booting issue on the Debian server
- Perform troubleshooting and diagnostics to resolve the issue
- Provide a detailed report of the steps taken and the resolution implemented

If you have experience with Debian server administration and troubleshooting booting issues, please submit your proposal.
