I have been banging my head against the wall for weeks with this problem.
The Problem: I have ubuntu installed on my laptop and I want to dual boot with windows.
I'm trying to install 64 bit windows.
I have tried tools such as winusb, and the newer fork of it, these did not work.
Using rufus or a similar tool, I was able to make a usb that would boot but only in MBR / legacy boot mode. I need to boot in UEFI mode.
for rufus I followed the instructions found here:
Afterwards, I followed the instructions found here:
This was the closest I have gotten, I was able to boot from the USB in UEFI mode, but it gives me an error:
Windows failed to start... Status 0xc0000225
I have tried using different USB sticks, and even different windows iso's. No success.
All the iso's I have been using have been windows 7 iso's, am I better off using a windows 8 or 10 iso? I would really prefer not to.
Does anyone have experience making a bootable windows 7 usb? If so what method did you use? Any help much appreciated.
Another note: The laptop came with windows pre-installed, I read on the ubuntu website that could be the problem. see the following link (toward the bottom of the page):
Does this mean it is not possible to dual boot with a laptop that came with windows pre-installed???
