Create Bootable USB drive

I constantly need to do this and I keep having to look it up, so I am putting it here so I know exactly where to go. Many older computers do not have DVD drives or in my case laptops have defective ones, so I need to create bootable USB's to install new operating systems.

Here are the steps:

Insert USB into machine (for modern operating systems - make sure it is 4GB or bigger)

Go to command prompt: (must "run as administrator")

DISKPART
LIST DISK
SELECT DISK
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS QUICK
ASSIGN
EXIT

Insert Windows OS DVD

:CD BOOT
CD BOOT
BOOTSECT.EXE/NT60 -------> (XP use BOOTSECT>EXE /NT52 )
COPY THE DVD CONTENTS TO THE USB

DONE
