Now I have Installed Linux as a primary operating system but now I need windows for some applications that wine can't run,I have a 32 GB flash drive I have installed windows 7 on it but it can't boot on windows I used to use EASYBCD to be able to boot to a windows VHD on USB but on Ubuntu I'm stuck and can't do any thing,Is there is a way to install windows 7/10 on USB without VHD to boot normally by selecting the flash drive from the boot menu and if there isn't how do I make my computer boot to the VHD on the USB without harming my Ubuntu system ?
Sorry for the Bad English and thanks in advance .

While the USB with your Windows OS is plugged in run this:
$ sudo update-grubGrub will scan all the attached drives for OS installations and add them to the boot menu.
Now your Windows USB installation will appear in the boot menu when you start your computer.
Proceedure: Obtain 64 or 128GB USB3 flash drive. Use mkusb to create a persistent flash drive with 1% persistence. Safely remove and replug flash drive. Copy existing virtual machine image, (.vdi), to the "usbdata" partition on the flash drive. Reboot into the USB Connect to internet. In Software & Updates, check "Software restricted by ..., etc.", then select "Updates" and ensure the machine will not will not automatically download or install updates. In Software Center install VirtualBox, From download the extension pack. Install the extension pack using VBox. Run VBox and select New, when you get to Hard disk, select "Use an existing..." and choose the image in usbdata.
Results: So far the drive is working in every computer I try, but very, very slowly in computers without USB3 and/or less than 4GB RAM. In a computer with lots of RAM some things almost seem faster, like orbiting complex rendered solids in AutoCAD. AutoCAD 2013 & 2016, SolidWorks, Cosmos FEA, Staad, Autoplant, Rhino and SketchUp all work Hilti Profis required a new serial number, and CAESAR II and CADWorx required reinstallation of hardware locks. Have had no luck connecting to a VPN.
