Can't dual boot Ubuntu 12.04.2 with windows 8 on Grub
I'm trying to install dual boot (Windows 8 and Ubuntu 12.04.2) using UEFI. Followed the instructions on https://help.ubuntu.com/community/UE...DD_in_EFI_mode, but the only way to get both Ubuntu and Windows working is modifying the boot option Priority in the Aptio Setup Utility.
If the Boot Option Priority is ubuntu (the other option would be Windows Boot Manager, that goes straight to windows 8), the computer goes to grub, and ubuntu the SO starts without problem. If the windows loader option is selected, the following error occurs:
ERROR: unknown command "DRIVEMAP'
ERROR: Invalid EFI filepath
this error was also occuring also before i ran the Boot-Repair api.
this is my Boot-Repair output:
