I have a Lenovo laptop with preinstalled windows 8 64bit- I attempted installation of Ubuntu 13.04 - however after installation I was faced with the GRUB loader. From the Grub loader if I try to start up the Windows Loader option it wouldn't load windows 8 and instead show me an EFI file missing error.
Alternatively if I restart the laptop and click F12 key I get to the Bootloader screen where I can choose to boot either:
Ubuntu Windows Boot Manager EFI DVD/CD ROM EFI USB
This is the only way I can choose to enter into either windows or Ubuntu plus after installing Ubuntu I've noticed that I now have a new unrecognised file format partition on windows 8 - I'm assuming its the Ubuntu partition.
The question is that how can I set up a dual boot screen that actually works here so I can choose to boot either windows 8 or Ubuntu?
