Error Description: [Errno 5] Input/output error
This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.

My current dumb solution is writing a bootable dvd, bypassing rufus / unetbootin. Can I have step-by-step working solution for creating bootable ubuntu 20.04 pendrive (in windows environment?)
https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#10-installation-complete - this is not working. (it is bootable in live session though) Rufus works with Linux Lite 5.2 so far. Unetbootin works with previous Linux distros 14.10 and before.
Thanks in advance!
