install Ubuntu to a sd card?

Question

Can I install Ubuntu onto an sd card and move it between devices? (like can I install Ubuntu onto an sd card and move the sd card to another computer and boot from it?)

Answer 1

Creating a Full install Ubuntu SD card from a Pre-built Image File that Boots BIOS and UEFI

• Download Image File: https://phillw.net/isos/linux-tools/uefi-n-bios/dd_unb_ubuntu-20.04_15GB_2020-06-26.img.xz

• Download Rufus*: https://github.com/pbatard/rufus/releases/download/v3.11/rufus-3.11.exe

• Double click Rufus exe file. (No need to install it).

• Select SD card as Target drive in Rufus.

• Select above Image File in Rufus.

• Click Rufus start button.

• Wait for flashing to complete... Done.

(Password is "changeme", change it),

The SD card should boot on almost any modern X86-64 computer.

Thanks to sudodus for the image file.

In Windows it may be necessary to install 7Zip before proceeding. Rufus will use it when working with the .xz image: https://www.7-zip.org/a/7z1900-x64.exe

*In Ubuntu you can use mkusb, Disks or Etcher to flash the SD card.
