I am new to this dual booting and Linux thing.
At first I got pre-installed Windows 8 Laptop with UEFI thing ( I heard its mess for dual booting )
I wanted to try Linux and its pretty cool :)
I downloaded the elementary OS : Luna (based on Ubuntu 12.04) 64 bit version and made its LiveUSB then I disabled Secure Boot from boot menu.
Then installed elementary OS . Everything went cool but I was unable to get a choosing menu . I was directly going into elementary OS but no option for Windows 8.
Then I installed Boot repair tool and I got message as "EFI detected. please check the option" ( I didn't knew what this meant , so I just ignored it )
Before doing anything I took a Boot Info summary : http://paste.ubuntu.com/7026387
And after that I selected Recommended repair and after that BOOM! I can't even use elementary OS and neither Windows 8 after restart.
The Boot Info summary after applying Recommended repair : http://paste.ubuntu.com/7026422
After restart I see three lines of efi read error like something and then something Grub , Minimal ... with a " grub> " after that . dunno what is this.
My Laptop : Samsung Series 5 NP550P5C
Right now I am using LiveUSB :P
ADVANCE THANKS !
