Ubuntu – How to create a bootable usb stick that is not read only

live-usb

I try to create a bootable usb stick. (I have an updated Ubuntu 16.04 LTS)
it seems simple enough to do this using Startup Disk Creator.

the usb stick is created and is working as bootable disk BUT now it has no write permissions!!

I had tried to remove the write protection – but nothing worked (chmod, dd, dosfsck, gparted, hdparm, fdisk, df …)

  1. How can I create Ubuntu 16 bootable usb stick with write permissions?
  2. How can I remove the 'read only' from a usb stick?
