Boot from VHD

[Midas]

Do I need to have a full working windows install on the computer (on a different hdd of course)? I need to boot off an external disk with ventoy and the vhd made through virtualbox on a pc with no existing windows install; it has linux. Is that possible through ventoy and vhd-boot plugin?

Bear in mind that installing Ventoy to HDD will erase everything previously on it, be it either Linux or Windows.

Apart from that, if you already have a bootable VHD, I see no reason why it would be required to have another OS installed -- the idea of using Ventoy to boot from VHD being exactly to work around this.

Also is Windows 10 LTSC 2019 iso supported for making the vbox vhd file? I need to cut all possible bloat and want to stay with official MS releases, not some modified ones available on the net, so chose this one.

While I personally haven't tested that particular Windows version, I also see no reason why you wouldn't be able to use it for this purpose -- me, I have successfully used both Windows 10 v1909 and v2004...
