You've pointed out my admitted ignorance as well as my inability to communicate what I am trying to achieve. I am apparently incapable of intelligently answering your questions. But I will attempt to make myself clear once again.
I want three live isos booting from one disk as if they were booting from single boot media. On an 8GB flash drive, this leaves room for storage and utilities. In as much as in my sphere of influence I run across those less informed than I in matters of computers and operating systems (believe it or not), some of which are shop owners who do some tech work on primarily Windows computers, I decided that I would include utilities which they already find useful in their work.
I know how to manually create bootable and multi-boot usbs using grub and syslinux. I sometimes use UNetbootin to create single boot usbs for purposes of testing and curiosity, but most often do it manually. I have attempted to use Yumi and some other multi-boot tools that did not work to my satisfaction. I had run across Easy2Boot but never paid it much attention (like some others it appeared to be ported to Windows, which I rarely use, and then only with great pain; so I passed it by) - I did not give it attention until this thread in which Distro-Don and wayne128 brought it to my attention.
When I went to create the usb I had in mind for the purpose for which I had it in mind, I followed the procedure I knew how to follow only to find that it would not work. I wore myself out scouring the web and finally posted to the Solydxk forums. Gaining no ground there, I posted to linuxquestions.org and then finally here.
Again, I envision an initial boot screen which serves as a portal to booting three isos as if they were on single boot media, and the system utilities as if they were stand alone as well (with the exception of PMAGIC, which it was simply convenient to include).
I have been experimenting with Easy2Boot to see if I could mask the initial boot screen and unattractive boot menus to my liking. But this too is a rather daunting task to me.
Your point regarding the error in my thinking in the use of the "fromiso" cheat code is well taken. Thank you.
I indicated my pleasure with your product by paying you for it. As it turns out it is good, but not good for what I have in mind.
So far as I know, I can boot the two debian isos from the same disk using grub, but not as truly live isos as I can chainloading to a single Debian iso extracted to a separate partition with syslinux. In addition, using grub requires that I boot to the utilities partition which requires (so far as I know) syslinux.
So I appear to me to be faced with a trade-off no matter which way I go. Use grub and boot desktops and the utilities partition, or exclude a debian iso, or exclude the utilities - or punt the whole thing.
I have some regret that I have brought my need to public light. Seems to be more trouble than whatever gain I initially saw.
Thanks for your time. If I have not made things as I see them clearer, then I most likely can not do so (for whatever reason, which in my 62 years of experience is never - never unilateral when there are two or more minds involved).
I have posted my progress to this point on the Solydxk forums. I am afraid that I have worn out, or of wearing out my welcome here. I think that I have reached the point where I will pursue this privately with any who may want to help me.
