[Solved] Sierra doesn't boot

Try to disable USB3 in the BIOS

Thanks BreBo, that worked, Sierra is booting now.
It's a shame though that USB3 doesn't work, is there a way to get it supported under Sierra?

Should I use the new MultiBeast 9.1 and install the kexts and Legacy Boot Mode again, or doesn't that affect the functionality positively?

In your case it doesn't affect the functionality positively.
