MultiSystem Boot CD
I have written a lot about MultiSystem CD.
It can be used in Windows but I am not going to waste time.
In Linux one can extract the SH file obtained from sourceforge, install it and run with ROOT permission.
It cannot be used as an ordinary user.
If you want to avoid root permission easiest way is to download version 9 from sourceforge, write the image into a CD (make sure it is 700 MiB), (why waste a DVD) and boot up.
It has Gparted too.
One must download all the images (ideally in the hard disk or even an external hard disk) beforehand.
NeBootIn let you download from the sight but it takes lot of time.
It is better test the isos by writing on CD/DVD.
What I do is install it on a FLASH Drive First using the CD. (ms.its.precise r9) or even an external hard disk and boot it on RAM and start adding one image after another to the Graphic Till or Cage.
Suse, Fedora and the new Debian (early 8 version supports live DVDs) do not support it.
Not to bother it tells you if it cannot make a live script.
If any of the distributions does not boot for any reason, what you have to do is to mount the flash drive on a Linux session and delete the live folder.
The name of the distribution remains in the Grub File but do not click the deleted one since the Flash drive or Hard disk hangs out looking for for the script.
If that happens wait a few seconds and PRESS the off button. If you do not wait for few seconds it might burn your RAM.
I did all this with on an old 32 bit IBM for three hours with only 1 GiB RAM, while doing (other) multi-tasks, nothing untoward happened.
That is the beauty of Linux.
Ten or more distributions in a Flash Drive is handy!
The mounting partition has to be FAT.
This was done on Debian 8.0.0
