How To Make A Bootable USB

First  find yourself a large enough and fast enough USB stick to use as your boot able media.

1. Open Run and then type DISK PART, to run disk part
2. Type in LIST DISK to list off all disks attached to your system. Make note of your disk# representing your USB stick
3. Type SELECT DISK # where # represents YOUR USB STICK
4. Type CLEAN to erase everything / every partition on the disk. Remember you validated what disk to clean in step 2, right?
5. Type CREATE PARTITION PRIMARY to make your new primary partition
6. Type ACTIVE to mark partition as active
7. Type FORMAT FS=NTFS QUICK  to perform a quick format
8. Type EXIT to close diskpart – unless you want to make more bootable USB disks

Next up – extract the source files (all files) of your  ISO file to the root of the USB stick. You can use whatever tool you prefer – I used to use WINRAR to open and expand them, or  use any image drive software to use MOUNT image, and copy all file to USB Stick.
You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature)
