First things first, you need to make your USB drive bootable in UEFI. You should :
- Plug in your pendirve ( minimum 4 Gig )
$ sudo fdisk -l
Find out your USB drive mount name from the output. Hint : You can always check for the drive size and spot that one out. The above command would give something similar to :
# sudo fdisk -l Disk /dev/sdc: 15.9 GB, 15854469120 bytes 255 heads, 63 sectors/track, 1927 cylinders, total 30965760 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x094a46d6
You will figure out that /dev/sdc corresponds to your pendrive. For the ease, I would continue with the assumption that /dev/sdc is your USB drive.
- Open terminal, move to the place where you have your iso file ready
- Use dd command to clone the iso to the pendrive
$ sudo if=ubuntu14.iso of=/dev/sdc
- The cloning will take few minutes depending on the speed of your pendrive. Once finished, give the final step :
That’s it ! You are ready with your UEFI bootable pendrive ! Now restart the system – press F9 or something similar to change the boot order and select :
SANDISK UEFI BOOT Ubuntu
or something similar from the boot menu and boot!
