Hello
I post here : the question is not a problem, only a curiosity.
I have installed Tumbleweed on a USB SSD stick.
That works but not always.
It works on my desktop that is in legacy.
I would use this stick on the laptop that it is UEFI only : the stick will not run.
The question is : How do I install Tumbleweed on my USB stick so that it works equally well on both ‘legacy’ and ‘UEFI’ PCs?
