I have been using
unetbootin to create bootable Linux USBs.
I want to do this manually using command line.
What is the procedure that unetbootin uses to prepare a bootable USB?
How would you go about manually converting an Ubuntu ISO to a USB?
Assuming you are on nix and the distro you are interested in is oneiric ozelot or above then the following should work
Please be triple careful with the argument to of.
Also please note, that the default ubuntu setup has the graphical usb creator installed, so no need for unetbootin.
