<< Solved >> Can boot into Mojave but not Sierra

[cinnamonxv]

Hello guys,

I managed to boot into Mojave and got it working. But after learning that the GTX 660 doesn't run well on it I decide to use an OS that does hence going back to Sierra. But I haven't changed my bios or anything and I keep getting this error when trying to boot into Sierra. Any help would be appreciated! Motherboard is Asus B85M
