Creating Bootable Media

 

Create a Non-Secure-Boot Bootable ISO Image

Things to know and do before we begin:

  • D: is your Windows installation files that are either on a DVD, USB Flash Drive or somewhere in the WIN8AIO folder which should be in the root of the drive chosen.
  • If it is on DVD or Flash Drive then it will be in the root of that drive. Example: D: or H: or whatever.
  • Make sure you have Windows 8.1 AIK installed.
  • Click the "Start Button" and type cmd
  • In the results you should see: Deployment and Imaging Tools Environment
  • Right click that and Open as Administrator

 

In the command window type the first command below using your drive paths but without the dot in the beginning:

  • oscdimg.exe -lWIN8AIO -m -u2 -bD:\WIN8AIO\boot\etfsboot.com D:\WIN8AIO C:\WIN8AIO.ISO

D:\WIN8AIO\boot\etfsboot.com is the path to the file named: etfsboot.com

D:\WIN8AIO is the windows installation files directory

C:\WIN8AIO.ISO is where it will create the ISO file

 

Create a Secure Boot USB Flash Drive

First you need to prep the USB Stick by cleaning it, petitioning it and formatting it. You will need the original ISO you got from Microsoft. This is great if you slipstreamed updates and need to make another secure boot USB Stick.

  • Open an elevated command and type the following without the dot in the beginning:
  • DISKPART
  • LIST DISK
  • SELECT DISK X (X is the disk number of the disk you need to prep)
  • CLEAN
  • CREATE PARTITION PRIMARY
  • SELECT PARTITION 1
  • ACTIVATE
  • FORMAT FS=NTFS QUICK
  • ASSIGN
  • Exit

 

Now we need to create the bootable USB Flash drive

First we need to copy the boot image from the original ISO to the USB Flash Drive.

  • Mount the original ISO that you obtained from Microsoft and make notice of the drive letter that the Mounted ISO was assigned to.
  • Also make notice of the drive letter your USB Flash Drive is assigned to.
  • I will use H: as the drive letter for the ISO image and I: as the drive letter for the USB Flash Drive. You need to change the drive letter to match the drives of you USB Flash Drive and mounted ISO image.

 

Open an elevated command prompt and type do the following and type the following using your drive letters without the dots in the beginning of each command.

 

  • H:
  • CD BOOT
  • BOOTSECT.EXE /NT60 I:
  • exit

 

Now open your mounted ISO image and copy and paste everything into your USB Flash Drive

You're done

Above for the ISO image maker you need to create the WIN8AIO folder in the root of whatever drive you choose and copy your windows installation files in to that folder. if you don't do that then you have to also change the command line entry to reflect the folder name you gave. Also remember to also change the drive paths to also reflect the location of the folder and file.

You can use the XCopy method if you'd like to, though I would suggest that you clean, partition and format with the method above prior to using the XCopy Method.

 

In Windows 8.x using XCOPY just open an elevated command window and type this command:

XCOPY D:  J: /e

D: is the drive letter of your mounted ISO

J: is the drive letter of your USB flash drive

Make sure you change these drive letters to match the corresponding drives on your system.
