The Unable to read partition as FAT error will appear during the Raspberry Pi boot process if the device is not able to read the file system from the SD card. This is a generic error that can have a few different causes, such as a corrupt file system or faulty SD card. In this tutorial, we will attempt to troubleshoot the error by looking at some of the leading causes and attempt to rectify them. The end goal is to get your Raspberry Pi booting from the SD card as expected.
A file system error is one possible reason that you may encounter the Welcome to emergency mode! error message when attempting to boot your Linux system. While in emergency mode, you can determine if a fsck (file system check) error is the culprit of your problems by examining the system logs with journalctl. Once you are sure that an fsck problem is to blame, there are a few troubleshooting steps you can take to remedy the problem.
NTFS stands for New Technology File System and is developed by Microsoft for use on their Windows operating systems. NTFS is not normally used on Linux systems, but has been the default file system on Windows for many years. Linux users are probably used to seeing drives with the ext4 file system, which is ordinarily the default and certainly the most widespread in the Linux realm.
The Linux operating system allows users to assign granular permissions to all files and directories. Ordinarily, it is sufficient to hand out read, write, and/or execute permissions to individual user accounts or groups of users by utilizing the chmod command. But it is also possible to set granular permissions on a per user basis by configuring access control lists.
Sometimes it is necessary to grant full user rights on an assortment of files in your Linux system. You may have dozens, hundreds, or even thousands of files on which a user needs read, write, and execute permissions in order to fully access and utilize them. In such scenarios, it can be useful to grant full user rights on an entire directory, which gives blanket permissions on all of the directory’s file contents and subdirectories.
Changing the username on a Linux system can seem a bit tricky at first. After all, there are tons of application settings, system services, file permissions, and configuration files that rely on the username in order to function smoothly. Suddenly changing the name can have adverse and unexpected effects on your system, and will cause certain things to stop working if you do not manage to change the username using the proper method.
Groups are an essential part of how discretionary access control (DAC) is implemented on Linux and, in general, on any Unix-based operating system. The creation, modification, and removal of groups are relatively straightforward operations which can be carried out using some utilities installed by default.
If you’ve been dabbling around with the Linux operating system, especially Ubuntu, you might have noticed numerous loop partitions appearing in your system. Often ranging in small sizes such as a mere few megabytes, you might wonder why these partition systems exist, what purpose they serve, and if they can be deleted to reclaim disk space.
Fdisk, cfdisk and sfdisk are command line partitioning utilities included by default in all Linux distributions. They provide different interfaces to the same set of functions: while they all can be used interactively, only sfdisk is script-oriented. They support DOS, GPT, SGI and SUN partition tables.
All Raspberry Pi models come with either an SD or microSD card slot. Since the Raspberry Pi does not come with any storage built into the device, most users will opt to use the SD slot to run the Raspberry Pi operating system as well as for storing additional files. But, the SD interface can leave a lot to be desired when it comes to speed.

If you want to run Ubuntu Linux on your system but you already have Windows 10 or Windows 11 installed and don’t want to give it up completely, you have a couple of options. One option is to run Ubuntu inside of a virtual machine on Windows 10/11, and the other option is to create a dual boot system. Both options have their pros and cons. A big advantage of a dual boot system is that both operating systems will have direct access to your computer’s hardware – no virtualized hardware and unnecessary overhead.
