Help! Yosemite Installation Crashes.

Recommended Posts


Hello All, 

OS X 10.10 released & I was pretty excited about the upgrade. Downloaded the Update from App Store & then noticed that it won't allow me to install on my MBR system. Sad! 

So I started digging Nireshs help here, & found MacPwn. However, I followed the instructions & made a bootable disk of the setup. 
I installed the chameleon bootloader & it booted. First, I've had that graphics glitch. So I entered in single user mode, Deleted kexts related to graphics. (My GPU in Intel HD & it's not supported). Rebooted & it booted just perfectly. I was happy enough that Now I can install it. So I've just erased my Maverics drive & tried to advance. & here comes the nightmare! 

Right after I press Continue after selecting Language, It shows me "Licence Agreement" page. When I press "Agree", it hangs for while, & then everything disappears. the screen then comes back with a Window saying, "Failed" & a log which is offered in case I would like to find out the problem. 

However, I'm just a simple user & don't understand this log messages. I though Niresh or anyone else here probably can help. 

Here's My Laptop Configuration: 

a) Intel Core i5 M450 ( 2.40Ghz~2.66Ghz)

B) Intel HD Graphics (1st Gen) 
c) Atheros 9285 wifi. 

d) Realtek RTL81XXX Ethernet

e) MotherBoard Chipset: HM57




Okay, since this is a Final rlz, & I couldn't find the kernel for this, i rather used "Kernel Beta 4"  & a custom MBR patch (found somewhere in internet but that was too for DP). I'm not sure which exactly broke it but I think some files are messed up with the MBR patch, may be ? 

I'm attaching an image of the error situation. Since currently can't access to HFS drives, couldn't share the log file. however I'll try to share shortly.

Looks like something went wrong earlier.  
I Tried once again using the DP4 Kernel patch &  Public Beta  "MBR_Patch". 
However, this time I successfully could run the installer but soon after starting the installation, I received the error "GPT Disk Required".

Hope to get a MBR_Patch soon from Niresh! :D :D
