I recently installed Ubuntu on my laptop(Sony Vaio Duo 13). The laptop ONLY has two USB slots in the back, no disk drive. A bit later I realized that I still needed Windows for programs needed in University. I tried using rufus to make a bootable USB that had Windows 8.1 on it. I tested the USB on a friends laptop and it went right into the Windows installation. When I plug the USB into my computer it says that "My Sony could not read media(USB/CD)." I was a bit baffled by this so I made a bootable USB with Ubuntu on it. Ubuntu was able to start up in grub and gave me the option to install it. I reinstalled it to see if that was the case. It was not, I still could not boot to the USB with Windows on it. If I do not boot into Ubuntu, I get into the grub command line. I have also changed my BIOS setting around to each combination of possible differences, no help. I fear that I have deleted or corrupted something in my MBR. If anyone could help, that would be amazing, as I have not been able to fix this problem in days. Nothing on google, reddit or anywhere else has made any difference.
Thanks!
