Then, close Secure Boot, as shown in the figure:
Finally, press the Esc key to exit.
2. Make a U disk installation tool
First, download the Ubuntu system you want to install on the Internet, which is a file with an ISO suffix. Then download the Ultraiso floppy disk tool on the Internet, which is a software for making a U disk boot installation tool.
Insert the U disk into the computer (note that the data in the U disk has been saved before this, and the next steps will clear everything in it) , and open the Ultraiso floppy disk just downloaded.

3. Create a disk partition for Ubuntu under Windows 10
In the win10 interface, press and hold the system key win+X to quickly open the function interface and enter "Disk Management (K)".
Move the mouse to the hard disk you want to partition, then right-click, a dialog box pops up, select the compressed volume, as shown in the figure:
After that, a prompt box will pop up, showing that the space size is being queried, as shown in the figure:
Wait for a while, after the query is completed, a dialog box will pop up, prompting you to select the size of the space to be allocated, as shown in the figure:
Determine the amount of your input compressed space according to your own available compressed space. This depends on your personal needs. The principle is that the larger the divided space, the better the better without affecting your personal win10 use. The reason is that once the divided space is small , it will be very difficult to change in the future.
PS: Be sure to carefully consider how much space is left for the Ubuntu system, and try to make it as large as possible, otherwise it will not be easy to change later. It is recommended that 50G or more, 100G or more is better .
During the compression process, do not turn off the computer, otherwise unknown errors may occur and the hard disk may even be damaged.
The compression is successful, as shown in the figure:
At this point, the disk space allocation is complete.

Note: Then you will enter this interface, where you need to choose other options , you can create and adjust the partition yourself, as shown in the figure:
Click Other Options Then, you will enter this interface:
The item that shows the free space is the area you just allocated on the win10 system. The size of the space is also the same as the size of the space you just allocated.
After that, it is the most important partition!
Start partitioning, specific steps:
swap partition:
Select the free disk , click + , select "Logical Partition" , "Space Start Position" , which is used to select swap space later , partition it with 16g space (for example), and then click OK , as shown in the figure:
/partition:
Continue to select the free disk , click + , all the remaining space is given to / partition , select "logical partition" , "space starting position" , which is used to select the Ext4 journal file system later . Select / after the mount point , and then click OK , as shown in the figure:
complete partition
After the points are divided, look at the line where the mount point is / on the interface, and the column in front of the device should show /dev/sdaX (X is an Arabic number), the specific number is different for everyone, it means your / Press the position of the partition on the hard disk, remember what number is behind the sda of this partition , and then install the boot boot device below: At the point, select the item of sdaX (X is an Arabic number) , that is to say , to install the boot loader in the / partition , as shown in the figure:
Then click Install Now , a prompt will pop up, don't worry, just confirm.
So far, the installation is complete.
