I have been trying with numerous methods to install Windows 7 alongside my 14.04 Ubuntu installation (64bit) which has a UEFI boot system, but none of the methods have worked yet.Here are some of the methods oI have tried:
1 - I made a bootable USB using the Windows7 USB-DVD tool on a Windows machine (everything seemed to work fine during creation), but when I go to load it, my machine boots right into ubuntu. I then went into GParted on Ubuntu and assigned a BOOT flag to the USB drive, but this didnt help. Windows installer just wont boot.
2 - I also tried using Unetbootin from my Mac machine, and all seemed well during the creation of the installer, but that would not boot either.
3 - I have also tried using WinUSB for Ubuntu, however I am getting a 512 error. While researching this error I read that "WinUSB only creates MBR bootable USB drives. If you want to install Windows in EFI mode a different method should be used".
