I inatalled Ubuntu in a new (Asus Zenbook UX305) laptop, with Windows 8.1 preinstalled, I choosed 'Install alongside' option when installing Ubuntu. Then I wanted to try ElementaryOS, and I chosen 'Delete Ubuntu and reinstall' option. The installation process went well until it ask me for space, it was recognizing many OS installed, so, I decided to stop installation to fix partitions.
After I fixed partitions I installed Elementary normally, but when I reboot I got a black screen, grub console:
When I was using Ubuntu I modified GRUB to launch Ubuntu without asking or showing any option (I think now Ubuntu is missing and GRUB is failing), but keeping Windows on disk.
I have Restored PC from Windows options, it suposed to clean the complete disk, but when I go to boot options in BIOS I still see a couple of options for Ubuntu, they fail, of course.
Now when I try to reinstall Elementary I get the same GRUB console. But I can start Windows if I 'clean' the disk.
I have also tried with Boot-repair from a LiveUSB, it shows a success message, but it's not working.
How can I repair this?
