I just installed Windows 7 on my new Asus N550JV notebook. It runs perfectly fine. Afterwards, I installed Ubuntu 13.04 from a USB stick, on the installation i chose "Install Ubuntu next to Windows 7". The installation worked fine and it restarted.
But then it did not show the GRUB menu but it automatically booted into Windows 7. So I googled around and found out that boot-repair could fix that problem. I installed boot-repair in a Live CD session and chose the recommended repair. It did some stuff and asked me to do some stuff.
After I restarted, I saw the grub menu. I could successfully boot into Ubuntu. But when I chose one of the two (why two? /dev/sda1 and /dev/sda2?) Windows 7 installations, the screen stayed purple (like the GRUB menu). I waited a few seconds and heard the Windows 7 login-sound, but the screen stayed purple.
When I chose the first of the two Windows 7 installations, the screen stayed purple but I could not hear anything.
Here is my boot-repair info: http://paste.ubuntu.com/6007744/
Hope somebody can help me
