I want to burn Ubuntu Minimal CD ISO to an old, 1 GB USB thumbdrive. Regular ISO doesn't fit. I already tried Startup Disk Creator and Unetbootin but both failed. I tried installing GRUB and pointing it to boot like this:
insmod part_msdos linux /linux initrd /initrd.gz
but it doesn't work. I also tried
dd but I ended up with not bootable drive.
Rufus worked on Windows with the same thumbdrive but I no longer use Windows.
What else can I do?
