Introduction
In this article, we will discuss an issue that occurred after installing a new M.2 drive on a desktop computer. The system was unable to start and went into emergency maintenance mode. We will dive into the context of the topic, covering key concepts and subtitles to provide a detailed understanding of the problem and its solution.
Problem Description: Unable to Start Kubuntu, Emergency Maintenance Mode
After installing a new M.2 drive on a desktop computer, the system was unable to start properly and went into emergency maintenance mode. The user reported that the hardware installation was done carefully, and there were no issues during the installation process. However, after the installation, the system showed the following error message:
Welcome to emergency mode! After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or "exit" to boot into default mode.
Investigating the Issue
The emergency mode message appears when the system encounters an issue during the boot process. To troubleshoot the problem, we started by checking the system logs using the following command:
journalctl -xb
This command displays detailed system logs, which helped in investigating the issue. After a thorough investigation, it was found that the issue was related to the newly installed M.2 drive.
Understanding M.2 Drives
M.2 (abbreviated from the Next Generation Form Factor, NGFF) is a specification for internally mounted computer expansion cards and associated connectors. The specification was introduced by Intel in 2013 and is maintained by the PCI-SIG, formerly known as the Peripheral Component Interconnect Special Interest Group. M.2 is the successor to the mSATA specification, which is also used for solid-state storage devices.
Fixing the Issue
To fix the issue, we needed to identify the correct driver for the M.2 drive. This involved checking the specifications of the drive and then installing the appropriate driver. After installing the correct driver, the system started up without any issues, and Kubuntu was up and running.
Preventive Measures
To prevent such issues from occurring in the future, it is recommended to:
- Verify the compatibility of the M.2 drive with the system
- Install the correct driver before installing the M.2 drive
- Check for any firmware updates for the M.2 drive
