spider93287 Posted July 10, 2014 Share Posted July 10, 2014 I previously used iAtkos ML2 to install Mac OS X (Mountain Lion) on my computer, and when booting iAtkos from USB I used the boot flag -s for it to work. Everything was working perfectly, though to boot Mac I had to insert a USB with iAtkos installed on it and boot from there. I tried to fix this by installing bootloaders.(I also had Windows 7 on another partition which would boot if the USB wasn't inserted) Then Mac wouldn't boot even with the USB inserted. So, I formatted the Mac partition and tried to boot the iAtkos installer again, though when I booted with the boot flag -s, after typing exit when prompted it would get stuck at "logout". If I do not use the boot flag -s it gets stuck at the apple logo (previously it had a cancel logo on the apple logo, though now it doesn't stop loading). My computer model and specs: HP Compaq 8510w Intel Core 2 Duo T7500 @ 2.20Ghz Nvidia Quadro FX 570M 2GB RAM 64-bit Processor Wi-Fi Adapter - Intel Wireless Wi-Fi Link 4965agn Link to comment https://www.insanelymac.com/forum/topic/299418-iatkos-ml2-reinstalling-mac-booting-from-usb/ Share on other sites More sharing options...
styrian Posted July 10, 2014 Share Posted July 10, 2014 Hello! I am wondering about, that your first install has worked with flag -s. This one is to set for getting to the single user mode. You should try it with the bootflags -f -v or -f -x -v. Have fun.

spider93287 Posted July 10, 2014 Author Share Posted July 10, 2014 I tried both the boot flags -f -v AND -f -x -v. They both give me a black screen. I also tried GraphicsEnabler=Yes -f -v and it gave me a changing pinkish to green colour on the screen.
