OT? copy live ubuntu iso image to usb for boot

[Ranjan Maitra]

Hi,

OK, I guess this would be unacceptable to ask in an Ubuntu mailing list
and I was trying to get help with a Fedora iso but since F15 has been
pushed back to be nice to mirrors because another distribution is
releasing just before the original date, I thought I would try my luck.

I am a loyal Fedora user but I have to install a Ubuntu live from an
ISO. So, with Fedora, I know what to do. Download the live iso image
and copy to usb using the following command:

sudo livecd-iso-to-disk --format --reset-mbr Fedora-14-x86_64-Live-LXDE.iso /dev/sdc

and everything goes through fine, with a bootable iso image created in
the process.

But when I try the following:


sudo livecd-iso-to-disk --format --reset-mbr xubuntu-10.10-desktop-amd64.iso /dev/sdc

I get:

Verifying image...

The media check is complete, the result is: NA.

No checksum information available, unable to verify media.

Which is actually far less output and an useless (in terms of live or 
install) iso on the usb. It is however recognized as a iso, but nothing
more useful than that.

Any suggestions on how to do this with Fedora? I prefer commandline
approaches.

Many thanks and best wishes,

Hi Ranjan.

For ISO images I can't dd on an usb stick I use Unetbootin[1]. It is in the 
Fedora repos and easy to use but has no command line interface. I have been 
trying to dd Ubuntu on an usb key but I doesn't work…

Regards,
Laurin

I suppose I would do the following....

1.  Create a Ubuntu virtual machine
2.  Use Ubuntu's own usb-creator tool

No the checksum is embedded in the iso at build time.

No that isn't going to work
livecd-iso-to-disk is only trained to work with fedora generated iso's
that buntu derivative uses a different squashed file system layout.

told'ya :-)

Ah the commandline always where something wonderful happens :-)
here's what I did:
mount the iso
cp all files & directories to your bootable stick/media
install grub or syslinux to stick/media:
note ubuntu uses grub by default so you should already find a usable
grub.conf, It can also be called menu.lst in /boot/grub
In my case I used syslinux and modified the config according to the original.

That can be avoided by using "--noverify".  IIRC, livecd-iso-to-disk
picks up the checksum info for the image from the Fedora website.
Obviously it won't have Ubuntu checksums, so you'll have to take it on
faith that the image is correct.

My guess is that the iso isn't truly an iso image (with a boot loader)
or, at least, the boot loader isn't compatible with a flash drive.

I believe Laurin suggested using Unetbootin.  I've had fairly good luck
with it myself, but not specifically in trying to get Ubuntu to work.
