Same story! I discovered Porteus (based on slackware) and used it from a 8gb sandisk usb for years. It shipped with xfce and was a blast to tinker with. I learned to compile software from source for it because the package management was non-existent. Taught me a lot. AAAND it's still live: https://www.porteus.org

I used a Porteus boot USB a couple of years ago to rescue the secondary hard drive on my Dad's ancient Windows 7 PC. The drive had partially died, making it inaccessible under Windows -- but 99% of the disk was still readable with Linux's NTFS support. There was some glitch that caused the GUI to lock up shortly after booting about 80% of the time, but if I could make it to the console tty it worked like a charm!
