The 17.10 ISO file is 64-bit only. The Ubuntu 17.10 minimal CD supports installation of Ubuntu on computers that have a 32-bit processor.
###How to make an Ubuntu Minimal USB using dd
While the minimal iso image is handy, it isn’t useful for installing on UEFI-based systems that you want to run in UEFI mode. The mini iso lacks the proper files for booting the computer in UEFI mode. Thus the computer will boot in BIOS compatibility mode, and the installation will be in BIOS mode.
Download the Ubuntu Mini CD iso file from the link on the Ubuntu Documentation Installation Minimal CD webpage. Download the Ubuntu Mini CD iso file for Ubuntu 20.04 from http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/current/legacy-images/netboot/mini.iso. Download the file called mini.iso to your Downloads folder. You can download the mini.iso file to wherever on your computer that you want, but download it to your Downloads folder so that you can easily run the commands in the following steps without changing anything.
Verify the md5 checksum of the Ubuntu mini CD iso file that you downloaded by running these commands:
cd ~/Downloads/ md5sum 'mini.iso'
If you are using Windows Subsystem for Linux download the Microsoft File Checksum Integrity Verifier tool from the official Microsoft Download Center. The Microsoft File Checksum Integrity Verifier tool is a command line utility that computes MD5 or SHA1 cryptographic hashes for files.
Check that the results of the command match the MD5 checksum of the mini.iso file on the Ubuntu Documentation Installation Minimal CD webpage.
Get a USB flash drive, 1GB or larger. Delete all the files from the USB flash drive. Mount the flash drive using the Disks disk utility.
Check in the Disks disk utility to find out the device name of your USB flash drive. This is very important because if you use the wrong device name in step 6, you will overwrite your whole operating system instead of writing to the USB flash drive. So check the USB flash drive device name twice. It should be something like
/dev/sd*where instead of the * character there is a lower case letter like a, b, c, etc. In the following step I am assuming that the device name is
/dev/sdc, but the device name of your USB drive could be something else like
/dev/sdbso check the device name of your USB drive twice and make sure that you get it right in step 6!
Open the terminal or Windows Subsystem for Linux version 2 in Windows 10 (which you have installed) and run the following commands:
cd ~/Downloads/ sudo -i dd if="mini.iso" of=/dev/sdc bs=4096 ## make sure that the device name of your USB drive is correct!
dd if="mini.iso" of=/dev/sdc bs=4096command should take only a few seconds to complete on most computers because the mini.iso is a small file, less than 60MB. The result of running this command will be a bootable Ubuntu mini USB.
Boot the computer from the Ubuntu mini live USB. The Ubuntu mini live USB should boot successfully and show a menu screen.
If you select the Install option (the complete install, not the cli install) from the menu screen in Step 7, then you can select other options during the Ubuntu installation process to download all the packages that you need to perform a complete Ubuntu installation. Select the Ubuntu desktop package collection from the list of predefined collections of software in the Software selection screen in the Ubuntu mini CD installer. When you restart the system at the end of the installation, you will have a working Ubuntu desktop with the default desktop environment.
