I am trying to install Slax onto a USB stick, I have followed the instruction to the dot, but it simply isn't showing up in the boot medium list. I am on Ubuntu 20.04 The USB stick is 8gb, with Master Boot Record partitioning, and formatted with ext4. I downloaded the .iso from the Slax site, extracted the slax folder, placed it in the USB stick, ran the script in the boot folder, and got a message confirming the process had completed successfully. After all that, I restart my computer, stick in the USB...and it doesn't show up in the boot medium list. What should I do to try to fix this? Thanks in advance.
