If you are currently using a GNU/Linux distro and fancy having a look at a live disk of Debian. Use the following to get it on a USB stick to test out.
$ sudo fdisk -l
Disk /dev/sde: 64.0 GB, 64016220160 bytes 70 heads, 32 sectors/track, 55817 cylinders, total 125031680 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x35c5644e
Device Boot Start End Blocks Id System /dev/sde1 * 64 2293759 1146848 17 Hidden HPFS/NTFS
So, in my case /dev/sde is a 64GB USB stick. Whatever is on it will be deleted and overwritten in this procedure, so make sure that I use a stick with large enough disk capacity specifically for this purpose.
Download an ISO image for the Debian installer either directly or via a torrent.
Then copy the ISO image to the USB stick using:
$ sudo dd if=debian-live-8.4.0-amd64-kde-dektop.iso of=/dev/sde bs=4M $ sudo sync
Then of course boot in and enjoy.
