View disk space usage
(2) Use the Usbinstaller when installing Ubuntu. Choose Try Ubuntu

See the partition of swap space, this is/DEV/SDA8
Restart your computer
If a swap partition is lost, you can see whether the swap partition is active (capacity is displayed) by using the "free-m" command in the terminal.
If not activated, the sudo mkswap/dev/sdax command (x is the number of the swap partition) can be activated.
The active UUID code is replaced with the UUID code of the original swap in the "/etc/fstab" file (which requires administrator privileges), and the mount can be activated automatically after rebooting.
