Topic: Can 2 ISOs of a linux distro boot off a DVD?
started by: seskanda
Posted by seskanda on Nov. 11 2010,03:43
I have the 32 and 64 bit editions of Ubuntu Studio in .iso format (of course). Each is 1.7 GB, i'm wondering if it's possible to put BOTH on 1 DVD, and boot from it. From what i gather, the folders are identical in the ISO's. I tried extracting the contents into 2 distinct folders, put in \easyboot\disk1, ripped the boot images from them, placed it in easyboot\disk1\ezboot, and made the ISO. But after testing it in VMWare, it only gets as far as the menu, and once i choose OS, it errors out.I have NO clue what's going wrong, or if what i want is even doable. Some help would be greatly appreciated.
Thanks in advance.

Well I’m unsure what and how you are going to use this large (1,7 GB) ISO-file.
But it is possible to launch Ubuntu Live ISO-file as it is (no need to extract anything from ISO-file)
Note: I have no clue or knowledge about structure in this large Ubuntu ISO-file (and I’m not going to download this large ISO
). However - in case you only use this Ubuntu as a “Live-system” (not installing it on harddisk).
If this is the case – then read post nr; 16 < HERE >
It’s possible you can launch ISO-file as it is
Test and report back if it works or not

I want to boot 2 ISOs (i386 + amd64) editions of Ubuntu Studio from 1 DVD.
I read that link you gave me, but i can't rename BOTH ISOs to UBUNTU.ISO in the same folder

Yes I know
– I suggest that you test one of them (for example 32-bit UBUNTU.ISO) and test if it is working as suggested. It is important that you use name “UBUNTU.ISO” as file-name and that letters are uppercased (CAPS=BIG LETTERS to file name)
If this first UBUNTU.ISO works – then do this:
1. In folder ezboot, extract from “ubuntu.zip” the file “ubuntu.ima” to folder ezboot.
2. Open “ubuntu.ima” and extract text-file “menu.lst” to folder ezboot (I use UltraIso to this operation)
3. Open “menu.lst” (you can use notepad) and change name from "UBUNTU.ISO" to “UBUNTU64.ISO” in all 3 places in “menu.lst”. Save changes to “menu.lst”.
4. Inject back “menu.lst” to “ubuntu.ima” and save “ubuntu.ima” as ubuntu64.ima in folder ezboot
5. Copy your ubuntu64-bit ISO-file to folder disk1 and rename file to exactly UBUNTU64.ISO (must be CAPS=BIG LETTERS to file name)
6. Create menu in EasyBoot and use menu command: memdisk ubuntu64.ima
7. Create ISO in EasyBoot.
Note: I do not have full knowledge how these ISO-files works – or if they can be launched by grub. Test and report back what happened

I tried what was written in the link, now it gets as far as a GRUB4DOS grub> command prompt 
I used the 32-bit Ubuntu Studio ISO, it's NOT a 'Live" version, could that be the problem? What else can i do next?

@seskandaQuote: ”What else can i do next?”
I finally have downloaded one version of ubuntustudio.iso-file – I downloaded “ubuntustudio-7.10-alternate-i386.iso”
I tested to integrate ISO with my script “easyboot-iso.script” and it launch Setup-program for Ubuntustudio correctly but ubuntu-setup fail to find my CD-ROM (when tested in “Virtual PC”).
Even if I extract all files to EasyBoot and use the reliable “standard” menu command “bcdw /isolinux/isolinux.bin” which also correctly launch Setup-program for Ubuntustudio.
But same problem occur – it fail to find my CD-ROM (when tested in “Virtual PC”)
It seems that we can use ISO-file as it is but having problem with CD-ROM drivers in UBUNTU

What is "easyboot-iso.script" and "bcdw /isolinux/isolinux.bin?? Are they in the .iso file? If yes, there are NO such files or folders, in the v10.10 iso i have.....

@seskandaQuote: ”What is "easyboot-iso.script" and "bcdw /isolinux/isolinux.bin?”
The "easyboot-iso.script" is a part of my collections of scripts that can be downloaded for free private use – however commercial use is forbidden.
In every post I put write in this forum you have below: “Download complete set of scripts including help file HERE”
It can’t be that hard to find if you low your eyes a little bit
Note: read carefully “READ_ME.html” in download
Quote: “there are NO such files or folders, in the v10.10 iso i have.....”
Well what do you have…..?
Anyway the "bcdw /isolinux/isolinux.bin” is commonly used to isolinux distros as it is common with a folder “isolinux” and various files and folders inside that folder including “isolinux.bin” that is the target for EasyBoot menu-command “bcdw” to launch.
I have not yet downloaded version 10.10 of ubuntustudio as it is such a large ISO-file in size – I used “ubuntustudio-7.10-alternate-i386.iso”.
But now it seems it doesn’t have same structure as version 10.10 if I understand your point correctly
I’m currently downloading this 1.7 GB large ISO - take some time
(DONE)I have to come back when I done some testing (takes long time and efforts as we are dealing with such large ISO-files).
-----------------------------------------------------------------
EDIT:
Unfortunately UbuntuStudio.ISO-file cannot be launched directly using easyboot-iso.script – we need to find the right grub-”parameters” and edit “kicker-image” created by easyboot-iso.script before it works.
At present time I have no clue what these parameters should be.
However – I tested integrating my Ubuntustudio to Easyboot this way:
1. Extract everything from UbuntuStudio-ISO-file to folder disk1
2. Created menu in EasyBoot and used menu command: bcdw /isolinux/isolinux.bin
3. I checked “Joliet” when creating ISO in EasyBoot.
This seems to work fine – but no I’m working on how to get next version of Ubuntustudio “onboard” EasyBoot – not that easy task!
For the record….
I downloaded ”ubuntustudio-10.10-alternate-i386.iso“ from < HERE >
In this ISO-file (based on isolinux) there is a folder “isolinux” and as expected a file “isolinux.bin” inside folder “isolinux”.
But you are claiming there is no folder “isolinux” inside your ISO-file - correct?
As a consequence I must ask you for download location of your odd ISO-file that do not have same structure as my downloaded “ubuntustudio-10.10.iso”
So where did you find UbuntuStudio-ISO-file that do not have folder “isolinux” inside ISO-file?

Ok, i saw link to download scripts, looks complex, i'll get back to that next post...Quote "I downloaded ”ubuntustudio-10.10-alternate-i386.iso“ from HERE

I downloaded v10.10 of Ubuntu Studio from the same link you did. And it DOES have an 'isolinux' folder along with isolinux.bin. The 'bcdw /isolinux/isolinux.bin' works for me, too. But, i have to extract the contents of ISO into \easyboot\disk1
Problem is, BOTH amd64 and i386 ISOs of Ubuntu Studio 10.10 have identical folder names. So, i can NOT extract them to easyboot\disk1, obviously. Is there a way to load the isolinux.bin straight from ISOs withOUT extracting them, that would be great

@seskandaQuote: ”Is there a way to load the isolinux.bin straight from ISOs withOUT extracting them, that would be great”
Unfortenetally I have not found a working grub-command (grub is used in the “kicker-image” that launch ISO-file directly).
Strange is that I can launch setup of UBUNTU-10.10.ISO-file
or use ISO without installing (run as a “Live-system) – but I cannot find out the right command-parameters for your UbuntuStudio.ISO-file Hopefully we can find out the right commands in future
In meantime you can only integrate one UbuntuStudio to your build – be patient...
However I must point out that possibility to solve this issue doesn’t look that bright
Note: in theory it’s possible to hex edit (change all folder names) but this is not any easy task
At least you succeeded to launch UbuntuStudio – a step in right direction
