thank you for giving me the oppertunity for writing this thread
anyway I have this modern laptop from samsung model is 300e4a-s0esa
core i5-2450m with 6gb of ram and nvidia optimus (intel 3000 + 520mx)
so far I was not able to boot my freaking system via the usb flash disk and I tried at least three ways so far but only one seems to work but I don't want to use it cause I need to find the problem with my method
I tried the method for the vanilla mac os x mountain lion and I did all the neccessory steps but it seems that my system does not see the bootable usb stick (I tried guid partition type but no luck strange even though my system is uefi compilant and I did set the ahci to manually enabled but I think I don't have legacy usb support)
I am now trying to make it mbr and redo the hole thing
I am doing this on a vmware image of lion 10.7.4 with a purchaced copy of the mac os x mountain lion app
any way I hope I can really boot to the installation this way
note : I selected smbios of the 9.1 mac book pro once and the other time I selected 8.3 mac book pro
I ma goin to keep this post alive until I completely reach the desktop of lion
ps: I really don't need to say this but the only working way for me was a tonymac with a cold boot but I ma not happy with it and it catches my systems as a mac book pro 8.1 but I am discarding this way of use
if any one have an idea about laptop support files to boot my installation please tell me !!!
sorry for my newbishness and thanks in advance

6 GB of Ram
Use the following boot flag and report back with apicture of what is no the screen:
Also what do you mean that your computer does not see the flash drive? Are you saying that in the laptop BIOS Boot menu it does not appear?

i only did put the usb-hdd option at the top then cd then sata hdd
and i do mean that bios skips the usb flash (guid partitioned) and boots directly from sata hdd
i am planing on installing the ML on a 32gb usb san disk cruz blade
thanks for your help i will report back soon i hope

what I meant was that I did change the boot sequence from the bios itself not from the boot menu because I don't have one
any way I managed to boot up my usb flash drive
the problem was that no one told me that it has to be mbr partitioned okay
but I had a panic but I don't know what it is
I took a picture of it and I will attach

thanks ifire for pointing out the extra folder
but anyway i was experimenting with the installation methods soo deep that i put alot of kexts in my installation folder
now i only did put the macbook pro 8.3 smbios.plist (only modified the cpu max speed to 3100 and the memory to ddr3 1333mhz) file in my extra folder and the themes folder created by the chameleon wizard
and vioalla i booted into the installation and i saw the new apple (ooh yeah finally) but i got stuck on the welcome screen because there is no KEYBOARD OR MOUSE support for my laptop (mouse is ps2 elan tech and the keyboard is a generic arabic enabled with functions keyboard)
what should i do now (is there any keyboard or mouse kext or something) ??
artur-pc : thanks for the heads up but i need to know what does this appleacpiplatform.kext do ?? should i put it even if i had a successful boot ??
appreciate all the possible help guys
Posted 15 August 2012 - 02:29 AM
and I booted into the installation successfully but before the apple logo I had two lines says that there was some problems during boot and there is a pause for 5 seconds then apple logo and the system boots
when I changed to verbose mode at first it says dsdt.aml not found and too much lines afterwards of kexts . is this okay ??
anyway I installed the mac os x mountain lion on my 32gb usb flash disk guid formatted and the installation completed successfully
i rebooted my system and then I got another panic twice !!!
what should I do help me please !!
I will attach the picture of the panic
Posted 15 August 2012 - 08:47 AM
however do you have an idea about that second panic I got
do I need to change something or to rick something in the chameleon wizard perhaps
please respond quickly if you can .
Posted 15 August 2012 - 09:17 AM

Posted 15 August 2012 - 10:07 AM
