====== Startup Disk Creator can’t see .ISO file ======

Rename .iso image to .img file

<code>mv imagename.iso imagename.img</code> or just mark the file, press F2 and change the name.

In some cases you have to move .img to Downloads folder in order for Startup disk creatorto see it
<code>mv imagename.img ~/Downloads/imagename.img</code>

Then open "startup disk creator" and choose appropriate USB (img should be automatically chosen)
