Putting 2 OS isos in 1 dvd

Linux distros are usually small

Meaning i could fit 2 or more in a dvd.

I want to put a 32 bit/64 bit distro of ubuntu and other distros but do not want to actually ''waste'' 2 dvd's since the isos are small enough to fit in 1.

Is it possible to somehow merge the isos and make them both bootable from 1 dvd?

 

What you want is a Menu System, right? So you can 'enact' whichever installation you want?

An ISO typically means, "This is a virtual envelope containing exact Sector-by-Sector Addresses for every bit and byte of data to create a CD or DVD." ONE CD. Or ONE DVD. To burn the one disk, I use the Image File - ISO - to re-create a sector-by-sector 're-creation'.

Now, I can store any number of ISO files onto a CD or DVD - however many will fit. But I'm burning a "Data Disk" at that point, not burning an "Image of an ISO disk".

If I wanted to create a disk holding THE CONTENTS of the ISOs, I'd 'unzip' the ISOs into their own folder structure, then I'd drag each Folder Structure to a DVD (or CD -depending on capacity requirements), then I'd build some simple batch-file menu. I might also create a bootable disk, too.

"Type 1 to install 64-bit..."
"Type 2 to install 32-bit..."
etc.

Is this what you mean?

The distinction is between Burning A Data Disk and Burning an Image-File Disk.

 

The 'easy' way is with easyboot from http://www.ezbsystems.com/easyboot/
the interface is a little hard to get used to, but it works. Best to modify one of the existing menus.

The later is actually what i wanted, as a ''data cd'' is kind of useless for what i want to use the disk for. Can you elaborate more a bit regarding the '' simple batch file menu''?

 

Try SARDU. It's a multiboot creator that can create CD/DVD's & usb

 

A great thing about threads like these are that difference experiences yield a wider range of options than I've spent time researching. I've grown so used to do it my way and it seems easy enough to me TO DO but I realize it takes a bit of programming and file-system choices. "What do you mean no one's using OS/2 anymore? SINCE WHEN-?!! Oh well, at least I still have DR-DOS..."

But here, I've got Foogoo and KABC's choices to research.

 

I know this is possible, as every month I get a multi-boot DVD with 3-5 distros to choose from; the DVD is a companion to my Linux Format subscription.

I can't find anything regarding multi-boot DVD, as most multi-booters use USB flash drives. A multi-boot USB stick looks easy:

You've got me curious now, though. Interesting question!

EDIT: Are you looking to do this from a Win Machine, or a Linux machine? I'm assuming Ubuntu, since you referenced the 32 & 64 bit versions; I found this link to success:

I can't figure out how to actually combine or put 2 isos in 1 dvd. This program seems like it just creates isos, or bootable usb.

I already have the iso's i merely wanted to put both of them in 1 dvd and both of them being bootable

 

This is from the SARDU website:

 

If you have something against buying easyboot, or you've just ignored my post, I found another tool & it's free. XBOOT

Very easy to use...

 

This was probably the best method as it is incredibly easy to use.

I was able to put about 4 different dystros

 

The xboot software doesn't support pear or bodhi linux distros though , actually most softwares don't seem to.

Which one is compatible with these, or maybe i am setting something up wrong

 

They're both based on Ubuntu. You could try putting them in as Ubuntu distros.

The QEMU preview feature doesn't seem to be helpful in terms of knowing if it will actually work on a dvd.

The preview option can see how the starting interface looks like and it can detect the operating systems i put but it won't launch into them so i can't tell if they work on a dvd or not.

For example the menu looks to work fine and then i see the ''pear os'' logo and it gives me an option to boot live cd, or the timer does it automatically. I press Ok the screen goes white in he computer and then i get a gray screen with bascally lines in it. It does this for every operating system i want to test before i actually burn the iso into a dvd.

I mention i can't tell if the iso is good because the last dvd i made one of the linux dystros worked while 3 others didn't. The preview doesn't fully boot any of them so i can't tell.

The first option i tried was Grub4dos ISO Emulation since it didn't have an option for the linux dystros. That didn't work, when i try to boot from the live dvd they just crash or get grey screens with an invalid error

I made an iso putting the files as ''ubuntu'' but like i mentioned the preview doesn't seem to fully boot any of them so i can't tell if it will work on the dvd. I have to get more dvd's to try it out but i rather not waste one.

Another thing when i put to put the file as ''ubuntu'' it increases the iso size by a bit more so i can fit less dystros.

I made an iso with 4 of them but it comes out to exactly 4.7 gb ( the size a dvd has). I am rather sure this won't fit in it, so i was trying to compress it but that only results in converting the iso into a different file type which can't be burned into a dvd.

Is there another method to compress the iso while keeping the iso extension?

How much space do dvd's actually have to store? I am guessing 4.3-4.4 gb?

 

Don't waste CDs, after you make an ISO test it in MobaLiveCD.

http://mobalivecd.mobatek.net/en/download.html

Or VirtualBox, VMWare, or Virtual PC.

Actual space on a DVD 4.35 - 4.39 GB.. different places have a different number

 

Regarding the xboot software and testing the isos in one of these programs neither work seem to work with bodhi and pear.

I tried putting them as ubuntu and grub4dos iso emulation and they will try to launch the live cd but crashes shortly after. I get a black screen with a small box with numbers and text saying something like '' cannot find medium for live operating system''
