I am unable to create a Bootable USB for Gentoo, using Netbootin on Ubuntu.

How can I create a bootable USB using the gentoo.iso file?

    Please describe what you mean by 'unable to create....using UNetbootin". What error are you getting? See http://askubuntu.com/questions/16277/how-to-create-a-bootable-usb-from-a-iso-file – Ron Sep 11 '15 at 06:32

    The answer to your second question is simple... your USB stick is probably FAT32 formatted. – C Schilder Sep 11 '15 at 07:23

    FAT 32 has a built-in limitation, which will deny you to copy files 4GB or larger to the USB stick. The 6GB is this one file? If the 6GB are multiple files of less than 4GB you should have no problem copying. – C Schilder Sep 11 '15 at 07:42

To avoid your copying problem reformat your USB stick to NTFS file system which does not have this 4GB limitation.

GUI solution

$ sudo apt-get install usb-creator-gtk
$ usb-creator-gtk

Command Line solution

Replace sdx by the usb device:

$ sudo dd if=<file_name>.iso of=/dev/sdx
