I have got a newly bought ASUS N56V with Windows 8 preinstalled.
I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader)
and Windows Recovery System (loader)
from the GRUB menu, these two errors show: can't find command 'drivemap'
and invalid EFI file path
and it goes back to the grub menu.
In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter.
Thank you!
