I just intalled ubuntu(the real one) and now i am unable to run on my previous win7.
As far as i know I didn't overwrite the windows partition.
If I try to launch windows it breaks down directly(with safe mode too).
Windows isn't able to start (I even lost access to the f11 menu) and asks me to insert a boot device (which I do not have sine it was pre-installed).

I followed some tipps and installed boot_repair which gives the following output http://paste.ubuntu.com/6525891/ (some EFI detected).
Altough I am a newbie I presume the error is coming from the ubuntu booter.

I am completely lost so thank you for any help :)
