Putting generated.iso on a usb stick

[Ole Ersoy]

Hi,

I'm attempting to put generated.iso on a USB stick.  I tried this:

[root@ole ole]# livecd-iso-to-disk /home/ole/generated.iso /dev/sdb1
Verifying image...
/home/ole/generated.iso: Could not get pvd data
Unable to read the disc checksum from the primary volume descriptor.
This probably means the disc was created without adding the checksum.Are you SURE you want to continue?
Press Enter to continue or ctrl-c to abort

ERROR: /home/ole/generated.iso does not appear to be a Live image or DVD installer.
Cleaning up to exit...

Any suggestions on how to go about doing this?  Also once the iso is on the stick can I just plug it in and go or are there other steps that must be performed before I'll get a menu?

TIA,
- Ole

I don't believe the generated.iso maps to what livecd-iso-to-disk
expects. I've not tried this in the past, so I do not know how to make
it work.

While attempting to figure out what to do with the generated.iso file the only documentation (mail list post) I came across mentioned livecd-iso-to-disk, so that was my first attempt.  Is there a more straightforward way to put the generated.iso file to work?

Either all .iso files or some generated in a special way can be
transferred in a way as simple as

cat file.iso >/dev/<sd-representation-of-usbstick>

Just used this with a linux live distro, probably the .iso has to
be generated in a special way - but worth a try.

Christian,

Just want to make sure I understand correctly.  So for example first create a bootable USB stick by using Fedora Live USB Creator.  Then once that stick is working, put the additional cobbler generated ISO onto the disk by doing:

cat generated.iso>/dev/sdb1

And now this will make the cobbler menu appear and enable me to select profiles?

Thanks,
- Ole

Looked up the instructions I had in mind, they are here:
http://wiki.grml.org/doku.php?id=usb 'Install using dd'.  
So trying this will use the
whole usbstick blockdevice (i.e. sdb instead of sdb1), will overwrite
existing partitiontables, and will not require any preparation of the
stick.

Its just a try however, I guess the iso has to be generated in a 
special way, not sure if that will work with the cobbler iso.

For this the 'cobbler buildiso' has to be used with the correct para-
meters, so supplied with the profiles you want - or maybe giving no
parameters at all will also result in the menu offered with all the
profiles.

Hi Christian,

I gave it a shot:

dd if=/home/ole/generated.iso of=/dev/sdb

It did put the generated.iso contents on the drive (And nuke everything else), but the drive does not boot.  I checked that the bootable flag was set using fdisk.

It was worth the shot.  At this point I'll probably just use the fedora liveusb to get the box running and then try koan do to a reinstall with the correct profile.

Thanks again,
- Ole
