and it gets worse! After installing, I had the exact same issue rebooting from the new system. I had to do that "nomodeset intel_idle.max_cstate=1" trick again just to boot at all then add it also in my grub configuration file, via terminal (and nano) so it actually works.
I can do all of this, it's not particularly difficult, but it *is* quite tedious and, I'd suggest, one of the reasons people aren't using Linux very much, this process is NOT for the faint of heart.
