Don't tamper with the disk, you will accidentally overwrite everything on the hard disk.
If you want to install the system, first use the partition tool to partition, and then use from image to restore the contents of the partitioned system, provided that you have backed up the partition.
If it is a new system with GHOST version installed, you should adjust the partition size first, and then install it directly. When installing the GHOST version of the system, there is usually an option to prompt you whether to partition. Generally, the new hard disk is directly divided into four areas. Just don't choose this option.

Commonly used computer phrases:
Disk to disk: copying from hard disk to hard disk is equivalent to copying files from two disks.
Disk to Image: It means backing up all the data on the hard disk.
Disk Slave Mirror: A mirror image in one disk is used to restore the whole hard disk, but it is different from the mirror image of GHOST. Don't make mistakes. It is generally wrong to divide multiple partitions into one partition. Remember.
Partition-to-partition: refers to a partition that covers another disk or another fast hard disk, and the size should be the same.
Partition to Image: Mirror the backup of partition to disk with suffix *.gho.
Partition from mirror image: of course, use the mirror image of the partition to restore the partition.
Check imagefile: it is to check the integrity of the image, such as what needs to be done before backup or recovery. Generally, it is rarely done.
Check the disk: Yes, check the hard disk.
