Is it possible/worthwhile to install Ubuntu on its own SSD so it can be swapped between machines as needed?

some of the modules in my university require us to install Ubuntu and I was wondering if it'd be possible to install it's own SSD to move between my laptop, PC at home, and campus desktops as needed, instead of having to transfer around files whenever I need them.

Would this be viable/smart/have any issues? I'm fine with installing it as a dualboot onto my machines, but the versatility and ease-of-use of having it as a separate drive seemed interesting to me.

Solution 1:

Creating a Full install Ubuntu SSD from a Prebuilt Image File

• 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 USB2 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 SSD should boot on almost any modern X86 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
