			= Bootable Media =
			== USB ==
			USB devices either "thumb" drives or card readers, usually for SD or microSD cards, have several advantages for booting OS:
			*generally much faster than DVD
			*bootable from UEFI firmware, whereas DVD might not be
			*higher capacity
			*reusable

			Special techniques are required to prepare bootable USB devices.
			== For General Users ==
			if the ISO image has been prepared as an '''isohybrid''', then the following tools can readily put it on USB device:
			*http://wiki.rosalab.com/en/index.php/ROSA_ImageWriter
			**this tool is also available for MacOS and Windows
			*https://en.opensuse.org/SDB:Live_USB_stick#Using_SUSE_Studio_Image_Writer

			A previously popular tool was "unetbootin". However this '''breaks''' isohybrids and should be used only with non-hybridised ISO.



			== Getting Techhnical ==
			It is now possible to put multiple bootable OS on a single USB device and then boot any from UEFI or non-UEFI firmware. This requires working knowledge of the boot parameters as well as running a number of command line programs. Detailed instructions are at:
