I have laptop with 2 HDD (Toshiba P870) and Windows 8 preinstalled on the first drive. Secure boot is enabled. When I install Linux (Ubuntu 12.04.2) on second drive it can't boot because of authentication problem. if I disable secure boot in bios - will I still be able to boot Windows 8?
Windows 8 boots normally no matter you disable or enable the Secure Boot option. It only fails to boot after changing the BIOS mode from UEFI to Legacy (without CSM support).
