iso image - how to make a correct bootable usb of a linux distro?

well I have been installing different distros of linux from by usb from time to time. And I always followed same method which until today stopped working for me.


So I use to format my usb with gparted into fat32 filesystem.


after that i will download the iso image of the linux distro i want to install (usually ubuntu)


open unetbootin and give it the location of my iso image on my hard-disk and location where my usb is (name of port).


unetbootin will usually do the trick for me and i can install the operation system on the computer by booting from that usb.


but today I tried this process several times and failed. Every distro gives almost same error.



  • can not mount on file-system.

  • (root) file system not defined.


other way I find on searching online was to use dd instead of unetbootin that too did not worked mostly it gives me an error that says isolinux.bin missing.


I even tried making a bootable usb using these guidelines
http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows
that too also did not worked.



  • and now the worst I tried fedore which installed perfectly and now will not boot from my hard disk (give some errors on booting first time)
    I tried installing fedora with unetbootin (as I use to do)

anyone can guide me how to make a live usb correctly? or tell me how to fix this error on fedora?


Thanks
