Hello I have tried pendrivelinux.com and unetbootin to install Ubuntu 12.04 LTS in a flashdrive. Each time it quickly jumps to run from usb drive before I can touch it when I set boot with F12 to usb. Then after about ten seconds it seems to freeze. I have to hard boot. I have formatted the 4GB stick and set it to 2 GB. I have tried to solve this and GRUB 2 has been mentioned in some of the readings but I know nothing about it. I do not know why I cannot intstall Ubuntu but wouldd very much like to be able to use it but not install it in my pc. It would be handy if the pc would not boot. Why can't the flash drive work?
