Bootable USB Media NotesRevisionas of Monday, 21 December 2015 at 02:30 UTC

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/
 mkfs /dev/

  • Install livecd-tools
  • Run it:

 livecd-iso-to-disk /full/path/to/CentOS_image.iso /dev/

  • 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!
