WTF? Hybrids? Half human and half machine? No. This means that now it will not be necessary to use a special tool to create an Ubuntu Live USB. Enough with clone the file ISO in the USB and ready. That easy. |
Fedora, openSUSE, or MeeGo ISO images have long offered the ability to create Live USB without the need for external tools. And now that feature of the so-called hybrid ISOs also comes to Ubuntu.
Until now, in order to create a LiveUSB medium, it was necessary to use the boot disk creation utility present in the various editions of Ubuntu, or failing that, our beloved UNetbootin.
However, Canonical developers are already using hybrid ISOs in Oneiric Ocelot Daily ISOs, and future previews will use this format as well.
Of course, the Ubuntu USB key creator can still be useful, since thanks to this tool you can create persistent storage space in those LiveUSB keys, something that cannot be easily done directly.

Hello cool blog, the only reason I keep chained to my pirated windows 7 is because of the Virtual DJ, but that's another story.
One question, does this publication mean that I can use Ubuntu from my 4GB pendrive, just copying the .iso to it?
Thanks Alfredo !!
Regarding your question: no, copying the file is not enough. Did you see when you burn a CD or DVD and it gives you the option of "cloning" it? Well, you have to do something similar with the ISO (which is an image of a disk) and "clone" it using the dd command on your pendrive. If you ask me, I keep creating the LiveUSB of your favorite distros with Unetbootin.
Ah! Regarding Virtual DJ, I recommend that you see these free alternatives:
mixxx ( http://mixxx.sourceforge.net/ )
terminatorX ( http://www.terminatorx.org/ )
Virtual DJ is probably "better" but they are not bad at all.
A hug! Paul.
I would like to know why this great idea did not occur to you before mmmm
And how do they work? How does the pendrive boot?
I don't know if you expect a technical answer ... but in the 3rd paragraph you can see how to use them :).
In addition to being ISO images that you can burn to any CD or DVD, they contain (in the first 512 bytes of the ISO that were previously zeros) boot sectors corresponding to an MBR and a partition table with 1 partition that ends at the end of the hybrid image (Among other changes, depending on the format, such as some grub stage or kernel image at the end of the ISO).
To copy it to a pendrive, all you have to do is copy it sector by sector, for example with "dd if = imagen.iso of = / dev / sdb" (as root) where imagen.iso is the image in question and sdb is the identifier of the pendrive (and not of a partition of the same, not sdb1 for example).
Once copied, when trying to boot from the pendrive, the system interprets the MBR (as if it were a hard disk) and the partition table and it works as usual :).
It was really about time they switched to this format, in Arch we have been with it for a long time and I personally always use it for the images of my live environments, it gives a lot of versatility on how to use the image without breaking compatibility;).
There is an application to convert a common ISO to a hybrid ISO, it is called: isohybrid
It is used as follows:
> isohybrid /image-path/image.iso
> dd if = / image-path / image.iso of = / dev / sdX
I used it to install openSUSE 11.4 on a netbook.
It works perfectly 😉
They no longer know what to do to get users, maybe people are already realizing what is happening with this distro.
I imagine this will be presented as the super-innovation of the century (I do not say here, I mean on sites like MuyLinux and the like, on the ones full of ubuntoos).
Keep looking for tactics for us to use your distro?
Removing the ShipIt has screwed up this Canoni $ oft riffraff
Because achieving it is not as easy as it seems ... maybe ... I don't know.
Exact! James is correct. Actually, the "appropriate" term here is not "copy" the ISO file to the pendrive (since this could lead the reader to think that copying the ISO file just like any other file is enough) but rather that what you have to do is " clone »the ISO (which is an image of a disk) on a pendrive.
I will correct that as it can lead to confusion. Cloning is achieved through the dd command, as James explains.
Cheers!! Paul.
Ubuntu ??? or rather Debian ????
This functionality was already added by debian before so I don't always see Ubuntu being the first to innovate
Tarin, read the article well. Nowhere does it say that Ubuntu is the first to incorporate this functionality. Rather, it explicitly says, “Fedora, openSUSE, or MeeGo ISO images have long offered the ability to create Live USB without the need for external tools. And now that feature of the so-called hybrid ISOs comes to Ubuntu too. " Debian can be added to the list of distros, of course… nobody said otherwise. Ubuntu is not original. On the contrary, in this respect it is coming VERY late.
A hug! Paul.
Because they like to copy, because there was the ShipIt, because people are realizing everything, etc.
