[SOLVED] Making Windows To Go bootable with Ventoy

[meilon]

Thanks for that recipe, though I went a slightly different road but the key was using VirtualBox. This is how I got Windows To Go to Boot via Ventoy from a working Windows 10:

1. Use diskmgmt.msc and create a fixed size VHD with at least 16GB
   
2. Use Rufus and a Windows 10 ISO to create a WTG install into that VHD in MBR Mode (don't forget to unmount VHD from diskmgmt.msc after Rufus completes)
   
3. Use VirtualBox (I used Portable-VirtualBox) to create a Windows 10 VM, use the VHD and Boot it with default settings
   
4. When the Windows 10 OOBE setup starts (language selection and stuff), stop VM
   
5. Put the VHD on the NTFS formatted Ventoy ISO partition and the ventoy_vhdboot.img into the ventoy folder on the same partition
   
6. Windows To Go boots via Ventoy in UEFI boot just fine!
   

Thanks again for the help! Now I finally have to carry only one drive with all the images on it!
