jpcuba Posted November 8, 2014 Share Posted November 8, 2014 Hi, thank you all in advance for your help. This is my PC Optiplex 755 Intel Core 2 Duo E6550 2.33GHz RAM 6gb galaxy Geforce 8400gs more specs: http://www.dell.com/support/home/us/en/19/product-support/servicetag/83X4HF1/configuration I followed tonymacx86 directions to get my installer, when I start I use -v cpus=1 which is what gets but further along in comparison to -x GraphicsEnabler=Yes, PCIRootUID=1, maxmem=4096, maxmem=8192, and npci=0x2000 Basically it reboots before I get to the installation. here's the video of whats going on http://youtu.be/Mc9hDd7KgLU Link to comment https://www.insanelymac.com/forum/topic/302464-install-reboot-osx1010-dell-optiplex-755-gpu-nvidia-8400gs/ Share on other sites More sharing options...
