smudger1767 Posted July 8, 2014 Share Posted July 8, 2014 Hi I have got Mavericks, on my USB which when I boot from the PC just keeps restarting before getting to the Instalation screen. I have allready tried these commands: @ the boot command PCIRootUID=1 PCIRootUID=1 -x I have 3 harddrives: Samsung EVO 256GB (Boot Drive) Has Windows 8.1 on it Western Digital 500GB Normal Files Western Digital 160GB will be for my install of OS X. In the Bios I have only the choice of UEFI USB KEY But I thought I should have a choice of that and just USB KEY. Neither of these worked I have also tried GraphisEnabler=Yes and No but I just get the pc re-boots. Motherboard:MSI Z87 GD65 Gaming BIOS:V1.10 E7845IMS V1.10 Steelseries Apex Gaming Razor Death Adder 2013 CPU:Intel Core i5 4670k PSU:SeaSonic 850 Memory:2x4gb 1400MHZ Graphics:AMD Radeon R9 270 Any help much appreciated.

smudger1767 Posted July 8, 2014 Author Share Posted July 8, 2014 Thanks Artur Downloading these now. Do I put these straight onto the USB that I'm booting from?
