i installed Ubuntu 13.04 as a dual boot on my samsung series 5 (NP353U4C) which came with windows 8 pre-installed. The problem is that i can't boot from windows 8 (loader) any longer, it just give me an error. I'm new to linux and i really need help to get the two working together urgently please.
If you can get into your linux then you can install boot-repair in your linux machine.
Open your terminal and type:
sudo add-apt-repository -y ppa:yannubuntu/boot-repair && sudo apt-get update
Press Enter and then the following command:
sudo apt-get install -y boot-repair && boot-repair
Most Probably this can solve your issue
No warranty: boot-repair modifies also uefi entries and so on if it works you will be happy, if not, you may be left with bigger problems than before.
