Linux: Create a bootable usb key

It's pretty simple and straight forward to create bootable USB on linux.

dd if=image.iso of=/dev/sdX bs=4M && sync

with:

• if: Input FIle (your ISO)
• of: Output File. /dev/sdX represent your USB key. Replace X with the letter of your volume (can be found with fdisk -l)
• bs: Block Size
• sync: make sure all data in buffer are written to disk
