Peterpower Posted July 29, 2011 Author Share Posted July 29, 2011 Ok Update, i added Madlons Extra Folder MacBook Pro MBP 8.1 I Got over the DSMOS arrived thing once, this wasnt repeatable. I got The Welcome Screen of the installation but the Pictures was cut in half, the left side of the picture was on the right and vice versa. The colour was a bright green and i couldnt read the Fonts because it was to bright. I redid my USB stick the same way as I done the first time. I get stucked with this DSMOS arrived thing again.

Peterpower Posted July 30, 2011 Author Share Posted July 30, 2011 Ok i think I tracked it down. When i Format my USB-Stick with MBR i can boot it but got stucked with DSMOS arrived. Somebody said me i ahve to format it with GUID, when i do this and install everthing in the same order as on the MBR stick I get a "Operations System not Found" Error when i try to boot it. I can boot it using a [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] CD but it jsut restarts after loading all the kext files from the usb stick. Somebody knew a solution why i cant boot from my GUID usb stick?

manbeard Posted August 11, 2011 Share Posted August 11, 2011 I'm thinking about attempting an install on my L501x, which is very similar (the model before Sandy Bridge), so I'll let you know what I come up with.
