AlperenAtasay Posted September 26, 2016 Author Share Posted September 26, 2016 I flashed .raw file to usb and installed that way.There are 3 partitions on my hdd.At first i installed Mac but it didnt install bootloader and when i try to boot it with setup usb it keeps rebooting after that message in the photo.My bios settings are fine theres nothing wrong.There's just one more thing, before i started to setup i had to remove some kexts from setup usb (kexts except NullCPUPowerManagement and FakeSMC) because it was giving an error like system boot up in nanotimes i dont really remember but it was something like this Link to comment Share on other sites More sharing options...
