1. File Names of hardware devices in Linux 2. Relationship between disk connection methods and device file names
3. Disk composition review
The smallest unit of the cylindrical file system, which is also the smallest unit of the partition. partitions are divided by the cylindrical number.
In linux, the file names are respectively (assume the hard drive device file name is/dev/sda): P1:/dev/sda1 P2:/dev/sda2 P3:/dev/sda3 P4: /dev/sda4. Windows corresponds to C, D, E, and F disks respectively.
Partition notes
Extended partition: Because the partition table in which the first slice is located can only record four data records, you can use the additional slice to record more partition information.
The partition partitioned by extended partitions is called a logical partition. It corresponds to the device file name in Linux.
Main partitions, extended partitions, and logical partitions:
Boot Process and primary boot partition (MBR)
Functions of Boot loader:
In addition to MBR, the boot loader can also be installed in the boot sector of each partition)
Summary:
If you want to install multiple boot times, you 'd better install Windows before installing Linux:4. Selection of disk partitions in Linux installation mode (very important)
