Prepare a USB Stick
To start from a USB Stick, it must be made bootable and formatted with ntfs. To do so, use diskpart as described in my other blog post here but use “format fs=ntfs quick” instead of fat32 filesystem.
Install Windows using ImageX
As you may now, Windows ISO Files / DVD-Roms contain an image file with the contents of the C:\ Partition. Now to install Windows 8 it’s only needed to unpack the filesystem to the USB Stick and create a Bootloader.
To make it easier, I’ve used the GUI Version of ImageX from AutoScript.com. In this Tool there’s a Tab called “Apply” where you can direct to the install.wim Image file and select the USB Stick as destination. By applying, GImageX extracts the filesystem to the Stick.
- Extract “install.wim” from the Windows 8 ISO file, Folder “sources” to a temporary location on your computer
- Use a tools like GImageX to Apply “install.wim” to the USB Stick
- Open CMD with elevated rights
- enter “bcdboot e:\windows /s e:”, where e:\ is your USB stick’s drive letter
