Download and install

Disk partition

Right click my computer – click management – select disk management
Win10 install Ubuntu 20 04 dual system
Right click the disk on which you want to install the system and select compressed volume
Win10 install Ubuntu 20 04 dual system
Enter the amount of compressed space and click compress. At this time, unallocated space will appear, which is the space for Ubuntu
If the disk space is insufficient, there should be at least 50g of space. Of course, if the space is sufficient, it’s better to have more. If the subsequent space is insufficient, it will be very troublesome. The space I allocate now is 120g. In short, more is better than less
Win10 install Ubuntu 20 04 dual system

Making a startup USB drive

Plug in the USB flash drive, run the downloaded Rufus, click Select, select the downloaded image, click start, and then wait for completion. This process may last more than ten minutes
