scratchspinmix Posted June 23, 2020 Share Posted June 23, 2020 Hello I am trying to install Catalina on a x79 Build. I get hung up on the boot screen with from what it looks like the normal boot screen but I only have option 1 to reset NVRAM. I do run Win 10 on another drive. I also can not seem to disable CSM mode on my motherboard. When I turn it off my motherboard does not post and I have to reset the CMOS. I am running the latest Opencore and following the Ivy Bridge guide. I searched high and low, I can not seem to find out why those are the only options. I started over and rebuilt my USB, still had the same issues. Anyone run into this? May just try clover instead, I am already one my second day trying to do this.
