I've got a lot of isos of distros and I want to chuck em all on one cd.
Then when I boot from it, I wanna to be able to select which iso to boot...

Demanding little bugger aren't I?

Any suggestions on existing CDROM ISO bootmanagers?

Maybe this would be possible on a DVD, but a CD can only store a max of approx 700 Mg of data. Considering that most individual distros won't even fit on a single CD (eg, Slackware 9.1 requires 2 CD's, Redhat 9 requires 3 CD's, etc) the idea that you could fit let's say 4 or 5 different distros on a single CD is mathmetically impossible. In other words you cannot fit, say, 4 or 5 gigabytes of data onto 700 megabytes of space.

It sounds like what you are trying to do is create a "Live-CD" which contains multiple distros. As a recall, a standard DVD can store approx 4.7 G of data (although blue light DVD's evidently have a higher capacity) but there's no way that I know of that this could be done on a single CD. Good luck with this, but what it sounds like you are trying to do is fit "10 gallons of water into a 2 gallon jug". Why not just set up a multi-boot system on your PC? -- J.W.

I'm not talking about full size multi disc distros. Of course that wouldn't fit.
I'm talking about 50MB installation distributions that download the rest during/after installation. Also, there are a couple of distributions that don't need installation and canrun entirely from CD.

So the problem isn't at all size-related. I think the tricky bit is that AFAIK there can only be one iso on a CDROM so I probably need to 'extract' the isos (isobuster?) to separate directories and create one large new iso and then get some bootmanager in order to be able to select between the distributions.

I doubt that I'm the first to come up with this, somebody out there must have done something like this or at least investigated into the possibilities.
