Hokkaido, Abashiri

You can create a bootable USB flash drive to use to deploy your OS of choice . The first step is to prepare the USB flash drive by using DiskPart, which is a command-line utility.

CHKDSK your drive

  1. Press the Windows key to open the Start Menu
  2. Type-in cmd
  3. Right-click on Command Prompt from the search results list
  4. Click Run as administrator
  5. When Command Prompt launches, type the command: chkdsk H: /f /r /x

The parameters for this command are:

  • /f option will attempt to fix any found errors
  • /r option will locate for bad sectors and recovery any readable information
  • /x option will force the volume you’re about to check to be dismounted before the utility begins a scan

If the C: drive is in use, type Y to run a scan at your PC’s next restart. If so, exit Command Prompt and restart the computer.


Create a Bootable USB Flash Drive

DiskPart is a text-mode command interpreter in Windows Vista, Windows® XP, and the Windows Server 2003® family. This tool enables you to manage objects (disks, partitions, or volumes) by using scripts or direct input at a command prompt.

DiskPart Commands

Before you can use DiskPart commands on a disk, partition, or volume, you must first list and then select the object to give it focus. When an object has focus, any DiskPart commands that you type act on that object.

You can list the available objects and determine an object's number or drive letter by using the list disk, list volume, and list partition commands. The list disk and list volume commands display all disks and volumes on the computer. However, the list partition command displays only partitions on the disk that have focus. When you use the list commands, an asterisk (*) appears next to the object with focus. You select an object by its number or drive letter, such as disk 0, partition 1, volume 3, or volume C.

  1. Insert a USB flash drive into a running computer.
  2. Open a Command Prompt window as an administrator.
  3. Type diskpart.
  4. In the new command line window that opens, to determine the USB flash drive number or drive letter, at the command prompt, type list disk, and then click ENTER. The list disk command displays all the disks on the computer. Note the drive number or drive letter of the USB flash drive.
  5. At the command prompt, type select disk <X>, where X is the drive number or drive letter of the USB flash drive, and then click ENTER.
  6. Type clean, and the click ENTER. This command deletes all data from the USB flash drive.
  7. To create a new primary partition on the USB flash drive, type create part pri, and then click ENTER.
  8. To select the partition that you just created, type select part 1, and then click ENTER.
  9. To format the partition, type format fs=ntfs quick, and then click ENTER.


If your server platform supports Unified Extensible Firmware Interface (UEFI), you should format the USB flash drive as FAT32 rather than as NTFS. To format the partition as FAT32, type format fs=fat32 quick, and then click ENTER.

  1. Type active, and then click ENTER.
  2. Type exit, and then click ENTER.
  3. When you finish preparing your custom image, save it to the root of the USB flash drive.
