On Windows use something like LILI http://www.linuxliveusb.com/ or unetbootin. On Linux multisystem http://liveusb.info/dotclear/index.php?pages/install or unetbootin or the startup disk creator on Ubuntu.. The last one is only for Ubuntu iso.
monkeybrain20122 mentioned several including one that is normally recommended - a semi "standard" - unetbootin. It runs on many OS's - Windows, Linux, Mac (if I'm remembering correctly), etc.. So the experience is the same across any platforms. It's simple to use, and you can point it to an ISO if you have downloaded one, or you can select what you want right in the unetbootin.
... and remember to format the USB to FAT32 before using UNetbootin, if you go that way.
I find it easy to use mkusb according to this
Ubuntu Forums tutorial "Howto make USB boot drives"
You get general instructions and a lot of links at this Ubuntu wiki page
and there is a detailed help page for Unetbootin at this link
Paul Sutton's Unetbootin how to
After I tried many programs to create bootable usb, I found out that unetbootin is best.
UNetbootin has a bit ugly startup screen, I prefer Startup Disk Creator from the Live CD.
Either way you can remove the Try/Install screen by replacing the contents of syslinux.cfg with:
for 64bit use "vmlinuz.efi"Code:default persistent label persistent say Booting a persistent Ubuntu session... kernel /casper/vmlinuz append file=/cdrom/preseed/ubuntu.seed boot=casper persistent initrd=/casper/initrd.lz quiet splash noprompt --
Don't need special programs to do it, it's built in.Code:sudo dd if=/path/to/iso of=/dev/sdX oflag=direct bs=1M
Yes, dd is very powerful, but there is a reason why it is nicknamed 'disk destroyer'. The shell-script mkusb uses dd under the hood, and help you doing it safely.
