What is the correct way to create a Persistent Ubuntu 20.04 Usb?

Question

I want to create a persistent Ubuntu 20.04 on my 8GB USB stick. Currently I have both windows and ubuntu as base Os. Better with windows.

Solution

You can install the current version of

• Rufus in Windows and
• mkusb in Ubuntu.

These tools can create persistent live drives from the Ubuntu 20.04 LTS iso file. See more details at the following link and links from it,

• How is it easier to make a persistent live drive with Ubuntu 19.10?

You can also extract and clone a compressed image file directly according to the following link,

• Xubuntu Core 20.04 LTS with mkusb 12.4.5 (mkusb-dus and mkusb-plug)

Yes, the same way for 19.10 and newer versions :-)

Welcome to Ask Ubuntu: Good question. 20.04 is taking up more space than 18.04. Extracting the ISO to USB require a root partition of almost 3GB. This leaves a little over four GB for a persistent partition, which is quickly filled up, and a NTFS partition. 20.04 persistent install also has a major problem with an unsolicited disk check that runs every boot and is difficult to stop.

It works with your 8 GB USB stick, but it would be a major step forward to get a fast USB 3 stick with at least 16 GB, even better with 32 GB. The following link discusses speed and size of USB sticks, which makes a difference for a persistent live system: help.ubuntu.com/community/Installation/FromUSBStick/pre. With a big and fast USB 3 drive, it is also a good idea to install Ubuntu like you install it into an internal drive (but into the USB drive).

Is it the same way as installing 19.10 , Or weather there is any new method of doing it.

[sudodus]

@Tylore, Yes, you can use the same methods that work with 19.10 also with 20.04 LTS :-)

Is there any difference in creating this with rufus and mkusb ? Which is better ?

[sudodus]

@Tylore, Rufus works in Windows. mkusb works in Ubuntu and Debian linux. The results (the persistent live systems) are not exactly the same, but rather similar. The persistent live systems work i similar ways. Please notice also that the systems made by mkusb-dus and mkusb-plug are also different from each other. If you wish, you can try all these methods and select the one that you like best. Maybe use the method that is most convenient for you because I think the persistent live systems should work well in all cases. If you want the extra usbdata partition with NTFS, use mkusb-dus.
