# Bootable USB Media Notes

Assume that your USB disk’s drive letter is D:

## CentOS/Fedora Bootable Installation Key

• Clear all partitions with fdisk

• Create a 100M primary, bootable (‘a’ key), FAT (’t’ and then ‘b’) partition

• Then create another primary partition to fill up the rest of the space

• Write changes and then issue:

  mkfs -t vfat /dev/<FAT Partition>
mkfs /dev/<Linux Partition>

• Install livecd-tools

• Run it:

  livecd-iso-to-disk /full/path/to/CentOS_image.iso /dev/<FAT Partition>

• Mount the Linux partition and copy the ISO file

• You’re set. Thanks, brah.

## On Windows

### Step 1 : Use diskpart to create bootable media

diskpart
select disk 1
clean
create partition primary
select partition 1
active
format fs=fat32
assign
exit


For the step highlighted above, use list disk to make sure that your USB stick is, indeed, disk 1. At this point, the USB stick has a primary partition and should be bootable. However, it doesn’t have anything to boot per se.

### Step 2 : Use xcopy to copy over the files to be booted

From the directory containing the boot files (these could be Windows installation files, for example), issue:

xcopy *.* /s/e/f D:\


Where D: is the drive letter of your USB stick. Et voila! Install away!
