If this sector is physically damaged, the hard disk will basically be scrapped.

Boot partition refers to the area where the computer is booted. If your c disk is the system disk of xp, and win7 is installed on the e disk, then the c disk is the boot partition, and the boot file has been written in it.

In general, a hard disk needs to be divided into several partitions, and each partition can be used independently. The boot partition (also known as the system partition) is the most important partition in the hard disk, which stores the computer's operating system and related files. It is a partition that must be read when the computer starts up.

System partition and startup partition can be a partition or not a partition. The key depends on how your system is installed.The boot partition is the partition where the operating system boot program is located, and it must be the main partition. The system partition is the partition where the operating system folder is located, which can be the main partition or the logical partition.

The area where the system is located is called the system partition. For example, if you install the system on the E disk, then the E disk is the system partition. After the system partition is installed, it will automatically change to the C disk. The boot partition refers to the area where the computer is turned on.

MBR This boot program identifies the active partition and boots the operating system. Main partition, extended partition, logical partition. As mentioned above, the main partition is defined by a 64-byte partition table in the main boot sector, and there can only be a maximum of 4. But in order to meet the needs of more partitions, extended partitions have been created.

Where exactly is the system boot area? Can't reinstall the virus in the boot area?

1. The boot area setting of the computer refers to the installation of the computer boot program (i.e. the boot record) on a specific partition or disk of the hard disk.

2. If it is a USB flash drive, start the computer with a USB flash drive (no, Baidu, maybe call your computer motherboard manufacturer), enter the PE system, open Diskgen, select your hard disk, click to rebuild MBR, and then save, exit, restart the computer.

3. Parsing: The boot area is when the hard disk is repartitioned and formatted, the boot record will be rewritten.Boot system. When we first bought a hard disk, we have no way to use it. You need to partition and format it, and then install the operating system before you can use it.

Question 2: To be blunt, what is the boot partition? The partition with the operating system (XP system) installed is the boot partition. That is, the so-called C disk.

3. The main boot area is located in the hard disk 0 magnetic track 0 column 0 sector, and the function is to save the main boot record and partition table. The partition boot area is located in the first sector of each partition. Its function is to save partition boot records and partition linked lists.

4. In general, the installer of the operating system will install the boot program in the first partition of the hard disk by default, that is, on the C disk.
