When the system is partitioned, the root partition stores system files and all files belonging to directories that were not assigned a dedicated partition. / (Root): The root partition stores all the systems when the system isn’t partitioned.The following table depicts Linux would be partitioned, their recommended minimum size, and usage. While this article focuses on the /boot partition, let’s use this opportunity to analyze the most common Linux partitions.
#How to create boot partition in linux install
That’s why many users decide to install only two partitions: The root partition for system files and the swap partition for the virtual memory.
If your calculation fails or your needs change, you may need to reinstall your system or storage devices. It is important to clarify the main disadvantage of partitioning storage devices is you don’t know how much space you will need in the future. Some users choose to leave up to 512 MB to the boot partition, more than that is indeed (unless for some reason you want to keep a kernels collection). Other users decide to dedicate the home directory to its own partition to prevent users from taking over the disk with personal files.īefore continuing with this article, the answer on the recommended boot partition size on Debian (Or any other Linux distribution) is 256 MB. Other partitions may be chosen just because the user considers different and specific file systems that would benefit his system. Of course, the same applies for other partition types for example /var, a directory we may want to dedicate its own partition to avoid logs from taking over our disk space. If you encrypt your / (root) partition, you will need to partition the /boot directory, so the needed files to boot remain accessible for the MBR (Master Boot Record, where GRUB is stored). Another reason to dedicate the /boot directory to its own partition would be the use of encryption methods. In such a scenario, before a boot problem related to files located under /boot, the user can reinstall the partition keeping the rest of the system untouched. The directory containing vital files for the boot process is part of this partitioning. The smart way to install Linux requires the user to partition the disk, mainly to isolate possible future problems in each partition. This article explains the recommended size for the boot partition on Debian 11 and other Linux distributions.
