ISO within ISO ? possible ?

Recommended Posts

Greeting, I'm a newbie in this "multiboot" field, please excuse my lack of knowledge.

With my research on most multiboot program on the scene, ie. isolinux, ezboot, bcdw, cdshell... etc, seems like none of them able to boot off a real ISO image, or am I incorrect ?? (except Acronis related ISO)

What I was thinking of acheiving is, instead of copying the ERD2005 content onto the harddrive, doing all the "loader.bin" modification.. etc, just leave the ISO as it is and start off from it just like any floppy image file, or is it impossible at this moment ?

Your advice is much appreciated.

At the moment this is not possible,

or to be more exact it is not possible with NT based OS, though it is possible with Linux and DOS, by means of Grub:

http://www.gnu.org/software/grub/

and/or syslinux/isolinux/memdisk:

http://syslinux.zytor.com/iso.php

(but it does not work on ALL systems)

It can be used with DOS based OS too, as well as this

somewhat experimental app by Gandalf :

isoemu

see here:

(original page is down, but you can find it here:

I think things are in the going about adding the isoemu feature to GRUB 2.

There is also this file for dos (chinese as well):

never tested it, though.

WinPE cannot boot from multi iso files!

As in a full featured OS you can ONLY INDIRECT access the mass storage device so a system booting is only poosible in a "Virual Mashine" such as VirtualPC/VMware.

Bur a boot manager in form of boot loader can act as a bios extension to add a extra cdrom drive to existed hardware, them boot from it(the code of bios extension will stay resident). But the "guest system" will also be restricted in access to storage hardware, once the code of bios extension was overwitten by the appl. of the guest system or itself, system will crash.

sorry for my poor english :blushing:

I'm looking for this solution too.

and i found magic iso maker could do this

but looks working with some iso-image only

or maybe i do it in the wrong way

hiren's boot cd iso, seagate hd tool iso working

linux iso and reactos iso not working

Magic ISO dose not have a extra boot manager, so it is IMPOSSIBLE with this programm to selecte a iso image file to "boot" at boot time.

The confusion was cause by the fat that MagicISO ONLY load diffrent boot sectors or boot image to boot. But here "boot image"="floppy boot image" or "no-emulation boot image". They are DEFINITIVELY NOT CD/DVD ISO-Image!!!!!!!!!!!!!

Hi,

The entire reason why its not possible currently, might lie in how the boot process is carried out.

Normally, a boot-image is loaded into memory, and then further instructions given by it, are executed. Now, lets say you had an ISO image of 690 MB to be booted from. As you might have guessed, that would require loading the entire ISO into memory, which is still not possible with most PCs today. Some day, when PCs have enough RAM as to load 690 MB up, and still have enough memory left for other operations, this might be considered realistically.

Hi all,

All are possible( ISO boot another ISO ): That is unbelievable with BCDW 201

I already made out a sole DVD( multiboot ISO ) with a boot menu choosing between Hiren7. ISO, True image80.iso, 2000 iso and XP install together with XPE SP2.

In Bcdw It is possible to boot iso files and ima,img,wbt files and it is possible to graphical menu, the only disadvantage is in graphical menu mouse will not work. if any one want a template that is a sample file with structure, ask me and let me know where to upload.

Could someone post examples of this here?

@perlabsrat

At the moment there is NO known way to boot a NT based system off an image file.

The only workaround is Ramdisk booting, do read this:

http://www.boot-land.net/forums/index.php?...=2692&st=26

Also, this thread is over TWO YEARS old, in these cases it is better to start a new thread instead of "bumping" the old one, if the original poster did not post the code in two years, it is unlikely that he will fulfill (or even read) your request. ;)
