This may sound similar question, but looks like my case is little different as the solutions suggested on this forum did not work (boot repair stuff). Basically after running that boot repair it created much or more grub entries but I cant load load it says "cant load image" while it is trying to access the windows Image.
Please find my boot repair log in the paste bin.
Also, I have installed in ufi mode 64 bit. And my windows 8 was working without issue before Ubuntu install. Mine is brand new Ace E1 (intel i3) laptop.
I will appreciate for any direction or help I really need this to be dual boot.
