Linux disk and file system management It is still important for disks and file systems, because all the data is stored in the disk. The correct partition of the disk and the management of the file system are summarized in my own notes, we hope you can provide more support. I.

Because the original Linux cannot be accessed, we create a Linux system installation disk and use "Try Ubuntu
