The fdisk USB utility can be run from a USB flash drive.  To do this you will need to create a bootable USB flash drive.  This can be accomplished using the HP flash drive tool that you can find on the Internet using a Google search:  HP bootable flash drive tool.  Once you have created a bootable flash drive you can install DOS and the DOS utilities along with fdisk.  This bootable flash drive makes a great technician tool to be able to retrieve NTFS files on Windows XP drives.

Fdisk NTFS (Fdisk Utility)

You can add free utilities to your bootable DOS flash drive, such as, Active NTFS Reader for DOS, for reading NTFS files from DOS and retrieving important data from non-functioning Windows operating systems.  I also have a YouTube videos that goes into this subject in more depth.

Fdisk CD

You can also create a bootable DOS CD to use fdisk again on a non-function Windows operating system.  Nero and some other CD burning programs allow you to create bootable CDs using DOS startup files.  This provides you another nice tool for accessing a computer that will not boot.

How to Fdisk

Fdisk can be a little challenging when you first attempt using it.  It does not have a friendly user interface.  I have also created an Fdisk DOS tutorial YouTube Video that you might find helpful.

GParted Partitioning Utility

Gparted is a free Open Source utility that you might find helpful.  GParted has a friendly user interface and operates very quickly for creating partitions and even resizing partitions without destroying your data.  I also have a GParted tutorial video you might find helpful.

WARNING:  This will remove some multi-operating system boot . . . → Read More: Fdisk MBR]]> The Fdisk MBR (master boot record) is an undocumented switch that can be activated by typing at the DOS prompt “fdisk /mbr”.  This will rebuild and rewrite the hard disk MBR file.  This can be very handy if the MBR file becomes corrupted or virus infected.

WARNING:  This will remove some multi-operating system boot functions.

At one time I used this feature daily in a lab to remove a virus that we were having difficulty cleaning from all our lab computers.  Today if you install AVG or one of the other top anti-virus programs you should be safe from MBR or boot record viruses.  The only other problem you might encounter is a corrupted MBR file, which can happen when some programs modify the MBR during installation.  To fix the MBR and get your computer to boot properly you would need to boot from either a DOS partition on the hard drive or boot from a DOS bootable floppy, CDROM, or flash drive.  DOS files can be retrieved from either MSDOS, Windows 95, 98, or ME.  You can even format a floppy disk and include the DOS (Windows ME) system startup files by formatting a floppy on a Windows XP computer.  You can also create a DOS bootable floppy by using a CD burning program like Nero to create bootable CDs.  To create a DOS bootable flash drive there are several utilities on the Internet that will format a USB flash drive and allow you to load the DOS startup files.  I use USB bootable flash drives daily to maintain lab computers.  I have also created several YouTube videos that can help you with Fdisk, DOS, and creating bootable flash drives:
