This question already has an answer here:
I'm new to Linux, currently using Kubuntu and trying to switch to Solus. So, I was trying to format the usb stick I used as a bootable pendrive to install Kubuntu, but I can't seem to recover my 8GBs. I've tried the KDE partition manager and GParted, but there is no direct mention of "Format" anywhere in both. I've mounted and unmounted the drive several times, tried to create a partition, GPT, MSDOS, ext4, FAT32, etc.
FYI, I created the bootable pendrive using Ubuntu's Startup Disk Creator. I don't understand how this works but I think there is a section of the drive that this program reserved that I can't access in any way. Or can I? If yes, how?
