GParted is an excellent partition management software.
As with all Linux based distros, especially disk editors, be careful.
Gparted can gum things up badly and without no warning if used wrongly.

I just finished putting the live i686 iso and the AMD64 iso onto the same USB stick. Together they needed only about 630 mb disk space.
I installed them using the UEFI version of Your Universal Multiboot Installer (YUMI), from <a href="https://www.pendrivelinux.com/yumi-multiboot-usb-creator/" rel="external nofollow">https://www.pendrivelinux.com/yumi-multiboot-usb-creator/</a>
The documentation on the GParted page does not mention using YUMI but it does work.
When you boot the USB stick you are offered a choice of which version to open.The AMD64 version booted fine on a win 7 uefi gpt computer. Have not tried the i686 version yet.
If this should be in "Freeware Rebooted" please move it there. Thanks
