Under Linux:
download NOOBS (approx. 960M)
extract into a directory
insert SD card into reader (8G minimum, up to 32G)
open a terminal window
su
(note that the root password is required)
gparted /dev/sdb
(assuming 'sdb' is the SD card)
using gparted delete all partitions on the SD card
create a new FAT32 partition filling the card,
if desired with a name like "NOOBS_1_4"
apply the operations; this erases everything on the card
exit from superuser
close terminal window
copy the NOOBS files into the top-level directory on the card
(warning: this takes a while, even on a fast SD card)
dismount SD card
insert SD card into Raspberry Pi SD card slot
power-up Raspberry Pi
NOOBS will run automatically on booting
Follow the menu instructions to install required Operating Systems
(Raspbian is recommended as a minimum; note this is ~3Gb)
Warning: running NOOBS wipes anything existing on the SD card
