Hi all,

How to burn a live CD on USB pendrive making the latter bootable.

I tried;
su -c 'dd if=/path_to/Live_cd.iso of=/dev/sdb1''X'' bs=8M'

/dev/sdb1 is the pendrive.

It burnt the live cd on the pendrive. But latter won't boot.

Pls help. TIA

Try unetbootin:

It's probably available from Ubuntu's repositories.

Hi,

Pendrivelinux provides simplified information to make it easy for anyone to install, boot, and run their favorite Gnu/Linux Distribution from a portable flash drive! Boot and run Linux from a USB flash memory'.

Live USB_Wiki 'A live USB is a USB flash drive or a USB external hard disk drive containing a full operating system which can be booted. Live USBs are closely related to live CDs, but typically have the ability to save settings and permanently install software packages back onto the USB device.' Links: 'system administration, data recovery method'.
Wiki includes a distribution table reference.

HTH!

This is your error. "of=/dev/sdb1''X'' bs=8M'"

Use simply the /dev/sdb and be sure sdb is that flash.

This assumes you have a hybrid iso image and that you don't care about the installed size to the drive and a few other yada yada's.


I used to use the www.pendrivelinux tools and many are good. However, every distro made in the last ten or so years can be installed to a usb. I simply use the distro's installer feature and be very careful where the boot loader goes. To be safe I always chicken out and use a virtual machine for this task.

A normal iso file won't boot when copied via dd to a usb stick. Fedora and a few other distros construct their iso files in such a way as to be bootable from both cd/dvd drives and usb sticks. Not sure what that "X" is doing in your dd command; when copying a Fedora livecd iso file to a usb stick, it looks something like this:

Hi all,

Lot of thanks for your advice.

Several years back I did many times using live CD to create bootable pendrive. No additional software was needed, only command lines and no need burning the *.iso on CD. Unfortunately I forgot the steps. I spent almost 2 days searching around my database as well as googling Internet without result.

The steps on;
http://www.pendrivelinux.com/install...nux/#more-4080

solved part of my problem. The live USB thus created couldn't boot. I suppose it needs the *.iso image burned on CD.

I played around with ubuntu-12.04-cloud-live-amd64.iso download on;
http://cdimage.ubuntu.com/ubuntu-clo...eleases/12.04/

without burning it on CD. I booted it on VM of VirtualBox without problem. I could play around the live cloud on VM. Then I ran the steps of "pendrivelinux" creating a live USB, also on the same VM. The steps went through without complaint. Unforturnately the live USB created can't boot on physical PC. I must complete this step making sure the live USB can boot a physical PC before going further to make it boot on VM. It is a different approach.

That is the complete story. I'm now stucked.

"This assumes you have a hybrid iso image"

A hybrid may be stated on the distro site or just attempted.


Otherwise the choice of live installers may work. Not all can work with a live installer.

Is there any possible breakthrough?

Again see this.

"This is your error. "of=/dev/sdb1''X'' bs=8M'"

Use simply the /dev/sdb and be sure sdb is that flash."

I meant the statement ought to be fully this.


From root or use sudo

dd if=/path_to/Live_cd.iso of=/dev/sdb


I make live usb's all the time in a virtual machine. What you may be mistaking is that you need to remove the VM hard drive and install the system then to the "ATTACHED" usb flash drive. Then follow the install program.

Hi jefro,

Tks for your advice.

I already have a live USB pendrive created according to;

The steps worked seamlessly. Now the USB pendrive can boot physical PC. However it can't boot VM. I created a raw disk to do the job, but still having a minor defect which I'm now trying to correct
