Deepin Tutorial: Deep installer EXPERT mode

Currently, Deepin 2014 is installed with the deep Installer. You only need to enter the user information, select the hard disk or partition to complete the installation configuration. Manual partitioning is not required, which greatly reduces the threshold for installing the Linux system, however, we still retain the EXPERT mode of manual partitioning. This time we will briefly explain the operations of the expert mode of the installer.

Mount point settings

When using the EXPERT mode, you need to have some knowledge about Linux Mount Points (partitions). If the origin of all Linux Mount Points is/(root directory),/must be set separately. User data is stored in/home. For user data security, we recommend that you set/home separately. Other mount points cannot be set separately./The partition size is automatically adjusted. In addition, some users may also need to set SWAP partitions. SWAP partitions are similar to virtual memory in Windows. The main function is to use some hard disk space as the memory when the computer memory is insufficient.

File System settings

You also need to set the corresponding file system for the mount point. The file system used in Linux is different from that used in Windows, so we cannot use a Windows File System. Here we recommend that you use the EXT4 file system, because the file system performance is balanced and stable.

Space settings

Next, we need to set the size of the mount point. The Deepin system requires at least 8 GB of hard disk space. However, we need to install some software after installing the system. Therefore, we recommend/allocate at least 25 GB of hard disk space. /Home is used to store user data except program, so we should allocate as much disk space as possible to/home. My approach is to allocate all hard disk space except/to/home. If your computer memory is small, you may need to set SWAP, then I suggest setting the memory below 2 GB to 4 GB. If the memory exceeds 4 GB, it is divided into 2 GB or not set.

System Boot Tool Installation

After the mount point is set, you need to set the boot program. If your motherboard uses UEFI, you must require your hard disk to use GPT. If your motherboard uses BIOS, the MBR must be used for your hard disk. The installer will help you select the solution by default, so we do not need to change it. If we manually change it to another location, the computer will fail to start.

The above is to complete the settings of the expert mode (Bios version), select "Install" to start the system installation.

FAQs

Q: only 100 M is required for the boot partition?

A: This is a very big error. At present, the size of the Linux kernel is much larger than before and is updated frequently. Several Kernel updates will occupy MB of/boot partitions, /If the boot partition space is too low or fully occupied, the Linux system may run abnormally or fail to start up. My suggestion is that if you really need to partition/boot, you must allocate more than 300 M and often clean up the old kernel. If you are a "lazy ", I recommend that you allocate/boot partitions by yourself regardless of/boot.

Q: The larger the SWAP, the faster the system runs?

A: The read/write speed of the memory is much higher than that of the hard disk. If the system uses too many hard disks to store data that should be stored in the memory, the system operation speed will be greatly reduced, we should set the SWAP size appropriately. (Source: Deepin)
