Many operating systems are installed via iso images deployed to removable media. While there are many tools available to accomplish writing/formatting iso images to bootable media, I prefer to use the command line.

Find the removable media path
If the system has already mounted the device it’s address can be found using fdisk. I was able to find the address of my new removable media device by it’s size:

$ sudo fdisk -l
Device     Boot Start       End   Sectors  Size Id Type
/dev/sdc1         128 122879999 122879872 58.6G  7 HPFS/NTFS/exFAT

The address of my removable media device is /dev/sdc1. Using this address you can write an iso image with dd (included with gnu linux). This examples uses an iso image that’s named bootable.iso (executed from the same directory):

# dd - Copy a file, converting and formatting according to the operands.
# if - read from FILE instead of stdin
# of - write to FILE instead of stdout
# bs - read and write up to BYTES bytes at a time
 
$ sudo dd if=bootable.iso of=/dev/sdc1 bs=4k

When the operation completes the removable media should be bootable. Leave a comment if you know how to make the process more verbose.
