Dual system partition idea:

• According to the previous experience of using Linux, even if you have 16G running memory, I am still slightly insufficient in daily development, so it is necessary to give 8G swap space.

• After half a year of daily use of the Linux system, for development, 60GB is more than enough as the /home directory, and about 60GB for the root partition is also enough. therefore:

  • / directory: 60GB
  • /home directory: 60GB
  • Swap：8GB

• Because the Linux system can easily access the files of the Win system, and the Win system is selfish and cannot be compatible with the Linux hard disk. Therefore, you can put large files (project data, videos), etc. under the hard disk of Win, and Linux can also access them anyway. So there is really no need to give Linux too much memory space.

Make the U disk into a boot disk, or restore the boot disk back to a normal U disk

• The boot disk is restored to a normal U disk:
