My System Info:
Notebook: Dell Inspiron 1545 (Inspiron 15 Series)

I used Unibeast and tried to install Yosemite. I am able to get to installation screen but it freezes while performing installation. Some times while erasing disk, Some times while extracting the files.. I waited a long time(6 hours) but there is no luck. Can anyone please help me with this. Thanks.
I used below boot flags, not all at a time but randomly depending on the error. Some times it went fine without any boot flags.
Using boot falgs -f -x -v , PCIRoot=1, Graphics Enabler=Yes, UseKernalCache=yes npci=0x3000
Also I used "command L" to see the installation process, The system freezes at extracting at some where around '200 to 400' line every time and last line before freezing was..
something about extracting file..no error
sometimes kexts signing error..
Thanks again for reading this mail. Please let me know your thoughts. Also let me know any one ever installed at least Mavericks with this System configuration. Thank you.
