How can the Ubuntu image file be restored after compression?

To restore an Ubuntu image file, you can follow these steps:

1. To decompress the image file: First, you need to use appropriate compression software (such as WinRAR, 7-Zip, etc.) to decompress the image file. Usually, Ubuntu image files are compressed in .iso format, you can right-click on the file and select “Extract to current folder” to decompress it.
2. Create a bootable disk or USB drive: Before installing the Ubuntu system on a new computer, you must write the extracted image file onto a bootable disk or USB drive. Software such as Rufus or UNetbootin can be used to accomplish this task.
3. To start the computer: Insert the bootable disk or USB drive with the Ubuntu image file into the computer, and then restart the computer. During the booting process, press the corresponding key (usually F2, F8, F10, F12, etc.) to enter the BIOS settings, and set the boot order to start from the USB drive.
4. Install Ubuntu system: Follow the prompts on the installation interface, select the option to install Ubuntu system, and then follow the instructions to complete the installation.

By following the steps above, you can restore and install the compressed Ubuntu image file to your computer. I hope this helps you!
