Re: opening iso file

You don't open it, nikolai, you burn it to a CD, and then you boot the CD. Make sure you choose "burn as ISO" or "burn CD image" in your burning app, NOT "make data CD". Also, make sure you set the speed to 4X (very slow, but required for good quality image).

Re: opening iso file

Assuming you are in kubuntu the default iso burning program is k3b

Re: opening iso file

Hmmm. Should anyone * need * to open an iso file without burning it to CD, say to get to the files, I posted one method here:

Re: opening iso file

Interesting. If you mount the ISO (Alt-Install CD), can you in fact upgrade from that mount? Never tried that, but very interesting. It should run as a normal CD, but would there be any interferences from the upgrade process? Hmmmmm....

Re: opening iso file

I've been searching on this issue - using the .iso file without burning to CD - in order to run it. Mounting an .iso is relatively easy, but it doesn't give you the ability to run it - you can browse the files only.

There are options available to create a virtual CDROM within which you can mount an .iso, but again, that doesn't give you the ability to boot from the virtual CDROM. That's what I've been searching for.

LiveCDs are designed to be booted, so if you can't boot the .iso file directly, then .....

Does anyone know how to boot an .iso file directly Is it even possible?

Re: opening iso file

Yeah, it's possible. I read about it on some site a while back. The guy mounted the iso, copied out the installer's kernel and ramdisk to /distro and copied the distro.iso there as well. He then edited grub to boot up the installer's kernel instead of the old one. The kernel mounts and runs the contents of the distro.iso that's in this directory when you reboot, thus completing the process.
Here's the step-by-step walkthrough.

BTW this won't work for ubuntu without this special ramdisk, not sure why.

Re: opening iso file

This method is not very much different from how I've been putting distros on flash drives, pretty much common sense. Copy the OS files into a partition (and you can get those from the iso w/o burning CD if that's the goal), locate the kernel & initrd into a /boot, construct a menu.lst entry for that OS, set up the bootloader to go, and that's it. If that OS requires any kernel options, that can be tricky for people not so versed, but you can usually find the right options somewhere (e.g., in the OS's own isolinux or grub configuration file!), copy them, append them to the kernel call. For example, Knoppix would not go without fromhd option when using a ramdisk; otherwise, I had to use root=UUID. Pretty much, common sense. It's amazing that it actually works, imho.

Let's see someone [else] here try the method with Kubuntu and report it to us.
