I feel stupid, but I want to install Kubuntu, as a dual boot for my windows 10 PC. I am a total rookie with linux. Maybe even less than rookie. I have 3 Flash usb sticks, but one of them seems broken, and the two others too small. I also have a USB card reader, where I can put an SD card in but I don’t seem to be able to boot from that.

I also tried a trick with Unetbootin, but windows wouldn’t let me boot from that either, even though it gave me the option to, on restart.

My question is, can I install a smaller version of Kubuntu from my 3,8Gb usb stick and upgrade to the newest version later, after it has been installed? I am not totally locked to Kubuntu, but I think that i have read that its the best version for beginners. I will easilly be convinved to another version though, if you guys think its better
