----efi system partition introduction EFI is conceptually very similar to a low-level operating system And has the ability to manipulate all hardware resources. Many people feel that its continuous development will likely replace the modern operating system. In fact, the founders of EFI limited EFI's ability to threaten the dominance of the operating system when the first version of the specification was introduced. First, it is just an interface specification between hardware and pre-boot software; secondly, the EFI environment does not provide an interrupt access mechanism, which means that each EFI driver must check the hardware status in a polling manner and need to explain The mode is running, which is less efficient than the operating system. In addition, the EFI system does not provide complex memory protection. It only has a simple memory management mechanism, specifically, it runs in the segment protection mode of the x86 processor. The memory is divided into a flat segment with maximum addressability. All programs have permission to access any location and do not provide real protection services. When all EFI components are loaded, the system can open a command interpretation environment similar to the operating system shell. Here, the user can call in any EFI application. These programs can be hardware detection and debugging software, boot management, and settings. Software, operating system boot software, and more. In theory, there is no limit to the functionality of the EFI application. Anyone can write such software, and the effect is more gorgeous and more powerful than the previous MS-DOS software. Once the boot software passes control to the operating system, all the service code for booting will stop working, and some of the running time service programs can continue to work, so that when the operating system cannot find the driver for a particular device at a time, the device also Can continue to be used. ----efi system partition deletion method (use the Diskpart command to delete the EFI system partition) Note: Please backup all the partition data of the disk to other separate hard disks before operation. All the consequences of the following commands are at your own risk. Steps: 1. Open Windows “ Run & rdquo;; 2, enter the Diskpart command to enter; 3, then enter the list disk command to enter to see which disk contains the EFI partition; 4, then enter the select disk N command to select the selected disk (N is the disk where you want to delete the EFI partition. If the disk containing the EFI partition is 3, the command entered is “select disk 3”;) Finally, enter clean and you can completely clear the EFI partition.
