I just tried to do a Dual Boot with my Windows 8 desktop computer by following instructions on YouTube.
At the start, I made a 200Gb partition from my 1TB hard drive. I booted Ubuntu 15.04 by using the USB technique.
In the video at 8:30, in the box, "Device for Boot Installation", I picked the Windows 8 selection instead of the 1TB Hard drive selection. It was a successful installation.
I restarted my computer, the GRUB screen appears. When selecting Windows 8, it just keeps sending me right back to the GRUB screen.
I need help trying to get to my Windows 8! I don't really care about the files in there, just a bunch of Steam Games but all that really matters to me is to be able to use Windows 8!
I also ran Boot-Repair but somehow didn't let me. It said something about using a live-cd or Live-USB.
