I have no problem with making Linux Live USBs, but how do I make an installation USB for Windows in GNU/Linux?
WinUSB can do that. It is a bit buggy but it gets the job done.
UNetBootin used to be able to do it too, but I'm not sure if it still works.
If both these options don't work, you could install a Windows virtual machine and create the ISO from there. Microsoft profides free Windows VM ISO's for 90 days.
Before that recommended reading: How can I identify a PPA is safe or not.
Also UNetBootin really can't be used to create Windows bootable usb sticks, always errors.
You can also create live usb using
Install from Software center (search
Or from terminal command:
sudo apt-get install gnome-disk-utility
disks--> select respective
Now click on More actions (double wheel shape) -->select Restore Disk Image --> navigate to
.isofolder --> select
