I know there are alot similar posts but none of them helped me. Here is my information from Boot-repair: http://paste.ubuntu.com/9319037/
The story is I tried to install Ubuntu while I was on Windows 8 and my partitions weren't recognized. I found some commands here (ask ubuntu) that helped me recognize the partitions and installed successfully ubuntu from LiveUSB.
After the first restart there was directly the error from Windows 8 that winload.exe is missing or corrupted. I booted again form the LiveUSB (ubuntu) and run Boot-repair in recommended mode. After the restart I got Ubuntu, but I can't boot into windows. Because I had partition for backup windows (sdb) when i select it it shows me the error with winload.exe. When I select windows (sda1) the screen goes black and nothing happens until I press the turn off button.
I have full access to the partition of the windows and the windows files and as I was reading I saw some posts that maybe Boot-repair changed the name or something but I couldn't find step by step how to fix that. I don't have windows 8 recovery disk.
I am noob at this so be simple or directly give me some commands and I will execute them, or some program maybe. I am sick of this because I killed two days tying to repair it. I would be grateful if you help me. Thank you.
