Hi guys!, I recently came across Ubuntu and i liked it, so i decided to install and try it on my computer. I did try out Live USB and i thought that i wanted to install it on my computer, but my system was, or had "EFI" so Ubuntu didn't recognize WIndows, so i found this guy on youtube who had a video showing how to do. I followed it, and started up ubuntu, but when i rebooted my computer to boot into Windows 8.1, the purple boot screen didn't show up, and it just booted into ubuntu again. I tried again with rebooting, and then the purple screen showed up, but the only option was "Ubuntu 14.04". When i launched explorer inside of Ubuntu, my Windows 8.1 hard drive were there. All my windows 8.1 files was still here, maybe windows it self, but it wasn't accessible. Pleeease help!!
