All you need to know about the EFI system partition

EFI system partition which is also referred to as ESP partition is a standard that has been developed to make sure that the hard drives as well as the external storage devices such as solid state drives adhere with the Unified Extensible Firmware Interface that is also referred to as UEFI and it was introduced with the GPT partition that was introduced by the Intel Corporation.

Purpose of the system

The system has been introduced to make sure that the boot loader that has been embedded within makes sure that the UEFI firmware loads the OS as well as the other utilities as soon as the system is started. The ESP is formatted using the system file whose utility is based on the FAT file system and for the same reason it is to be noted that the user should also make sure that the file system specification is treated differently from the original FAT specification. The boot loader also makes sure that the system loads the files that are required to be loaded before the boot process completes. In addition to all this it is also to be noted that the user should also make sure that the errors that are related to the start up and the utilities are also resolved using this boot system. In short the boot loader is the necessary part of the OS which makes sure that the best and the state of the art experience is what is provided to the user in relation to the system.

Working of EFI system partition

The use of the EFI file system is something that differs from system to system and for the same reason it is also to be noted that Linux, Windows and even Mac have their own way of treating with the program but it is for sure that all three support the program to full extend and make sure that the best and the state of the art services are provided to the user in this regard. Following is the overview of the working of all the OS mentioned in combination with the EFI system partition.

  1. Linux
  2. GRUB 2 and elilo are the two UEFI boot managers that are used for the Linux OS. Without limiting to the main EFI partition or the file system these boot managers can make sure that the kernel images and other system utilities are accessed in a manner that is considered to be the best and state of the art in this regard. The EFI boot stub is also another part that is to be considered when it comes to the Linux kernel as it makes sure that the OS boot loader is used in line with the system requirements and the traditional boot loaders are overcome which were once used by the MBR system. It is therefore clear that the Linux has also regarded the MBR file system as outdated and the developers have made sure that the OS is transferred to GPT partition and hence the EFI system partition.

  3. Windows
  4. The requirements of the windows are somewhat different from the original EFI system partitions as it urges the users that the boot loader is to be installed in the first partition of the drive which is definitely not the requirement of the original EFI system partition. The commands on 32 bit and 64 bit OS also differ in this regard and to make sure that the partition is accessed within the new 64 bit OS the user needs to make sure that the mountvol/ s command is run in order to make the configuration changes which would make sure that the boot loader only loads those files that are required by the users and the other utilities are disabled.

  5. Apple-Intel
  6. On Mac and Intel branded systems the user needs to make sure that the best and the state of the art service is accessed by making sure that the EFI partition is not used for booting the system. With reference to the OS that is under discussion it is advised to make sure that the EFI system utility is used to stage the upgrades and the updates that are posted by the company to make sure that the OS is updated on regular basis. To run the OS in flash firmware mode it is advised to make sure that the directory EFI/APPLE/FIRMWARE is used to make sure that the needful is done in the best manner. One more interesting fact in relation to the EFI and Mac is that even if the user deletes the EFI partition the system will still boot but on the contrary the system upgrades will fail so the system will not be upgraded till the EFI partition is reconfigured.

How to delete an EFI system partition

For some users this issue might be of importance as the option is sometimes grayed out and the novice users are worried about the disk health and the current status.

It is also referred to as protective partition which the windows disk management is not able to delete but no to worry about the issue as there are several ways to make sure that the partition is deleted and the readable partition is created in this regard. In order to make sure that the needful is done it is advised to make sure that the following process is applied to get the desired results in easy and fast manner:

  1. The disk number from where the partition is to be removed is to be noted for reference as this will come into work afterwards in this process:
