Getting errors when booting iso's/.img from USB? Use this method

**Dlambert** · September 11th, 2011

If you are having difficulties burning and booting an iso or img file from a usb drive, try this method.

But first I recommend that you download your iso or img via torrent, to prevent corruption if possible.

Open a terminal and type:

Code:

cd /home/YOURUSERNAME/Downloads

Replace USERNAME with your username, and Downloads with the folder in which your iso is located.

Then, with the usb drive inserted:

sudo fdisk -l

To detirmine when your USB drive is mounted (for me it was SDB)

Then:

sudo dd if=NAME OF ISO of=/dev/sd[REPLACE WITH THE RESULT OF PREVIOS STEP]

DO NOT, I repeat DO NOT, enter something like sdb1. Because it will not work, you have to use the root of the drive. Which would be sdb instead.

This guide comes straight for mips, I just thought I'd post it for everyone to see, I take no credit.

If your having problems doing this, use:

Code:

su

And enter your password to use root

Ubuntu root is locked by default. And it is preferrable to use sudo or gksudo for root privelege.

see ROOTSUDO

as for using a .iso or .img file for USB, easier to download and use Unetbootin, it is in the repos.

This works for hybrid ISOs which some other distributions already have. Note that it totally erases your flash drive.

The daily ISOs for the Ubuntu Oneiric development cycle (and all official Ubuntu CD releases going forward)
for i386 and x86_64 platforms will be now spun as hybrid ISOs.
