I just installed Ubuntu 12.04.3, and afterwards Ubuntu boots perfectly (even with SecureBoot still enabled etc), however selecting Windows 8 leads to the common errors:
Secure Boot forbids loading module from (hd1,gpt6) /boot/grub/ntfs.mod no such device 564525C65425C5233 unknown command `drivemap' invalid EFI file path
If I use Boot-Repair to fix grub, then disable SecureBoot both OS boot. However, I'd like to know if there is a way where I can have Win 8 boot whilst leaving SecureBoot switched on for the added security benefits? I'd also like to understand better what exactly is going on here, how can it be SecureBoot causes issues for Win 8 loading here, but Ubuntu is fine..
