When distro hopping...

So I've been distro hopping for the past couple of weeks, and I always googled how to format my boot drive and then write an ISO to my flash drive as bootable (boot-able, I'm getting a wrong spelling indicator with the "bootable" word XD) USB drive. Since I did that very frequently lately, I thought of just adding a blog post that would serve as my notes/reminder.

Formatting Boot-able USB

You won't be able to detect a boot-able flash drive in Linux (ie. in Nautilus or Dolphin), while in Windows, Explorer would only show a very small portion of it. My flash drive is a 16GB flash drive, but Windows Explorer only lists it as a 5.12MB drive. In order to re-use the flash drive, we'll be using the terminal for both Linux and Windows... Here are the steps:

In Linux

  1. Execute lsblk -l
    This should list all your drives, including your flash drive with the corresponding "original" disk space. It would usually be sdX (X here is a variable, your flash drive might be listed as sda or sdb, etc.)

  2. Execute sudo dd if=/dev/zero of=/dev/sdX bs=4k && sync (replace X again)

  3. Execute sudo fdisk /dev/sdX
    Just press o to create a new empty DOS partition table.

  4. Press n to create a new partition. Just use the default options (ie. create a new primary partition, with the size as the whole flash drive's space)

  5. Execute lsblk -l again, you should see a new partition under your drive (ex. sdX1)

  6. Execute sudo mkfs.vfat /dev/sdX1 (replace X) to format it, and then eject your drive :) (sudo eject /dev/sdX)

In Windows

  1. Execute diskpart

  2. Execute list disk
    This should list all drives connected to your computer. Select the drive that has the same disk space as your flash drive. We will call that as disk X for the sake of this post.

  3. Execute select disk X

  4. Next, execute clean

  5. And then let's create a partition using create partition primary.

  6. Open up the explorer, navigate to your flash drive, and then Format the drive :)

Creating a boot-able Linux flash drive

In Linux

  1. Execute lsblk -l to get the correct drive name

  2. Then we have to write the iso to the flash drive:

# umount /dev/sdX
# dd if=/path/to/downloaded.iso of=/dev/sdX bs=4M status=progress && sync

In Windows

I personally use Rufus, because we would still need to download cygwin to do this in the command line. Since I'm going to download something extra anyways, I'd rather go for the easier route.
