Host: macOS

Create windows image

I haven’t success install Windows via the created usb disk with this method, I always have issue “Windows could not prepare the computer to boot into the next phase of installation”, but it works for some others.

I have created this simple script, run it like: <script>.sh <image_location>

Before use this script, make sure:

  • Only 1 usb disk inserted
  • Install wimlib

usb_disk=$(diskutil list external|head -n1|cut -d ' ' -f1)
diskutil eraseDisk MS-DOS "${DISK_LABEL}" GPT "$usb_disk"

hdiutil mount "$IMAGE_FILE"
rsync -vha --exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/* "/Volumes/${DISK_LABEL}"

mkdir -p "/Volumes/${DISK_LABEL}/sources"
wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim "/Volumes/${DISK_LABEL}/sources/install.swm" 3600

Download the latest Ventoy release, extract the file and open VentoyGUI.x86_64(Depends on your system arch), select the target USB disk, and select Option -> Partition Style -> GPT, then click Install. You will see two mounts: Ventoy and VTOYEFI. Copy the ISO file of Windows installer into Ventoy. That’s it.
