This step should not go into too much detail. Whether you are installing a windows or ubuntu system, making a system USB disk is necessary. The blogger is using the system USB disk installed by UltralSO. You must download the Ubuntu image before installation. You can choose which version you want according to your needs.
Enter the BIOS and set up the USB boot. This step is also a necessary step to install Win10. Different brands have different setting methods. You should set it according to your own model. After setting, the U disk can be automatically started after plugging in the system disk.
Win+X enters the disk partition directory and sets the disk partition prepared for the Linux system. You can set it up according to your own needs. The picture shows the disk partition of the blogger's Dell gaming computer. Because it has a solid-state hard drive, two disks are displayed. On an ASUS computer, only one disk is displayed. Here you need to set up a large partition first (the blogger set up 150G according to his own needs). The following partitions are set when installing Ubuntu. The red boxes are the partitions after the dual system is installed.
After installing the system, the blogger found that he could not open Grub to boot the dual system. After searching online for a long time, he found that Win10 quickly started by itself, so he had to do this step first under Win10 (but he did not find that this was needed when installing Dell. step).
Hold Win +
After choosing to install, remember to select other options. The region and language can be set by yourself. It is best to choose an English keyboard for the input method option.
The next step is to set up the partition. The blogger initially used the partition settings that he found online, but after setting up the last partition, he found that the last partition was unavailable. After searching online, he found that there was only one disk. The reason (it seems that a disk can only have two primary partitions, so this problem was not discovered when Dell Gate was installed). Then you need to follow the settings below to install normally.
16G swap space logical partition
60G/Ext4 log file system logical partition
500M /boot Ext4 log file system logical partition
/ Primary partition (remaining space)
After that, the installation and settings will be normal.

After that, you can happily operate Ubuntu.
