Hey Guys,
I´m trying to install Sierra on my Alienware Alpha 2nd Gen. It has the Intel i5-6400T processor and a GTX 960 (desktop grade) graphics card.
With bootflags "nv-disable=1 cpus=1 PCIRootUID=1 npci=0x3000 GraphicsEnabler=No" it gets stuck at:
I tried to disable every USB Controller and unplug the M.2 SSD as well as the SATA SSD. Nothing happened, still the same issue. Trying with bootflag "GraphicsEnabler=Yes IGPEnabler=Yes" it gets stuck much earlier without showing any useful feedback.
I have no idea what to try next so I hope you guys can help me!
