jamesss Posted October 22, 2012 Share Posted October 22, 2012 Hi everybody, im trying to install mountain lion 10.8 on my PC (i5 2300, asus p8H67, nvidia 560ti) I've made a booteable USB drive from a vmware mountain lion based system, with ###### and the original mountain lion from the app store When i tried to boot with it, i can only reach the screen with the apple logo for a few seconds, and then, the computer goes to "sleep" (with the monitor suspended), and nothing happened, i also tried with -v , but the same thing happened Any idea? Thanks a lot, and sorry for my english Link to comment Share on other sites More sharing options...

djavocado Posted October 30, 2012 Share Posted October 30, 2012 I did the same as you, made a bootable USB with ML and encountered same problem, few seconds before I get to the install screen, my monitor went into sleep mode.. Using boot flag -x worked for me (i7 860, Intel DH55TC, Nvidia GTX570). But others, as I have read, had luck with other bootflags. Good luck!
