I have run into a bit of trouble installing Ubuntu 13.04 on my Asus Zenbook UX51. Under Installation type I selected "erase disk and install Ubuntu". Then it asked me to select a drive. I had two options - Serial ATA RAIDORST (stripe) - 17.7GB Linux device-mapper (striped), and Serial ATA RAID0SYS (stripe) - 238.4GB Linux device-mapper (striped).
I first chose the first drive that I mentioned. It seemed to install correctly but when I rebooted, it started up with the original windows 8 OS. So then I reinstalled Ubuntu using the second drive and now when I reboot it goes to a strange screen telling me that a cable is unplugged.
I have tried running the boot-repair but that did not seem to help anything.
If anyone could help me out, I would be very grateful!
