I used wubi to install the ubuntu version (taking 10.04 as an example). This morning, I had to spend two hours to install wubi into the ubuntu 10.04 system on my computer. Now I keep a record and forget it. 1. Prepare the CD and DVD images of the system to be installed. 2. CD is named ubuntu-10.04-desktop-i386.iso. 3rd. Use winrar virtual optical drive software to separate wubi.exe from the CD image and place it in the same directory as the image. Run wubi.exe in 4、and select the path, size, username, and password to install. 5. Do not restart after installation is complete (this step is important). Rename the DVD image as installation. iso, replace the installation in the intall folder in the installation directory ubuntu (default, or your own system name. iso file. 6. restart the system, go to the ubuntu system, and continue the next installation. Note: It is best to disconnect the network during this process.
