thanx for ur answer




I was found another usefull post where some1 said:


 When you are in the screen where you have to choose the disk where install Maverick, press the button "Customize" in left-bottom. There will appear different voice to choose. Go Graphics and tick the one that say "Backup all Graphics Kext" or something like that. Then, complete the installation again. It will work smile.png.pagespeed.ce.6NyMHoRtUg.png!!

1 Gray screen with apple logo and "working..." icon.

2 Crash by  [AGPM Controller] Unknown Platform.
