I have a live cd version on a flash drive. My question is, can I install a full, living and breathing (and mostly personalizable), version of Ubuntu on a flash drive? I tried yesterday, it went through the process, but at the end it said it had problems installing the bootloader. I don't figure I would need a bootloader on a flashdrive version of it, since it would use the bootloader of the computer it was plugged into. What I want is to be able to customize a flashdrive version, with programs like: arp-scan, nmap, testdisk, etc. If anyone could help me, I would appreciate it.
