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.

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, Ranjan
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…

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. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@nerd.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - "I understand Windows 2000 has a Y2K problem." - ----------------------------------------------------------------------

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.

I suppose I would do the following....
1. Create a Ubuntu virtual machine 2. Use Ubuntu's own usb-creator tool
