I have made my pen drive bootable. I am 100% sure there's nothing wrong with the pen drive.
I have a DELL inspiron n5010, I had tried installing ubuntu 12.04 four months back but I dont remember where i went wrong.
When i boot my laptop and enter the boot menu ( by pressing the f12 key ) I don't get an option to boot from usb. What do I do?

  • In the BIOS menu, you need to change the boot order so that the USB flash drive, which is usually called USB-HDD in newer computers, is the first entry in the boot sequence, and then save your new BIOS settings and exit the BIOS setup. – karel Aug 13 '13 at 17:27

First, download the Ubuntu installer image.

Then, on Windows:

  1. Download and run the Universal USB Installer

Or, on Mac:

  1. Convert the .iso image file to a .img using hdiutil

    hdiutil convert /path/to/ubuntu.iso -format UDRW -o /path/to/target.img

  2. Transfer the .img to the USB drive

     dd if=/path/to/downloaded.img of=/dev/diskN bs=1m

See: Instructions for installing Ubuntu from a USB drive.
