I've used different USB bootable programs like Unetbootin to put an iso image into my USB and went into the boot menu to change the boot device but I get the message "missing operating system" before it starts my current OS (Kubuntu) again.
According to this (http://www.webupd8.org/2010/10/create-bootable-windows-7-usb-drive.html) article: Some users have reported that some recent Unetbootin versions no longer let you select an USB drive formatted to NTFS and by formatting it to FAT, the Windows 7 installation fails.
What do I do? [Deadline for Windows 10 update is tonight!]
EDIT: I've already tried downloading WinUSB as well (one of the many programs I've tried) and I never got past downloading it because I get
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
in the terminal.
EDIT 2: I went into sudo nano /etc/apt/sources.list
because I was going to try to comment a CD-ROM source, but it already was:
# deb cdrom:[Kubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial mai$
so the source code is not the issue..
The terminal tells me the problem is:
W: The repository http://ppa.launchpad.net/colingille/freshlight/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
I'm still looking for a way to solve this.. :( This is not a duplicate because I cannot download winUSB.
tried disabling the ppa from the source code and running the steps again
sudo add-apt-repository ppa:colingille/freshlight
sudo apt-get update
sudo apt-get install winusb
nothing new. Posted another question.. https://askubuntu.com/questions/804582/cant-download-winusb
