Gparted looks good from here. KL is the only install on this stick?
while booted into F96 and with the new KL stick plugged in, please run blkid and post the terminal output
a screenshot of the rox window when rox is opened to the install directory please, and
what exactly do you see reported on your screen when you try to boot the KL stick. (if you only have the one computer to work with), maybe a photo with your phone?
