Lenovo Y480 Installation Issues

[Al3j0]

Hello people

My laptop is a Lenovo IdeaPad Y480 actually with EFI and Win8 installed.

I had created the USB HDD Mountain Lion Installer according with Tonymac86 UniBeast Guide (In Other PC) and when I tried to install it on my laptop I get this error:



I don't know if this error is for the EFI or for the Video Card

I hope you can help me with this issue

Thanks

Try another USB port. USB2 if possible.

I tried on the USB2 Ports and I got the same error

I got past that error by using "-v PCIRootUID=1" as my boot perams. I didn't get completely installed yet. Once i get into the installer the customization menu is blank and the install fails.

Still trying though.

I've tried many times with different boot options, all USB ports and I got the same error.

I want to ask you if there is a newest ML version that have more drivers or if I should to format my HDD, or if with this new topic about EFI - UEFI interface should I apply a patch to my BIOS system.

I hope you can help me with this issue

Use after your previous parameteres USBBusFix=Yes GraphicsEnabler=No -f -x -v

after a lot of reads, I found a command that finally works

EHCIacquire=Yes

After installation I apply Multibeast Boot Loader and when the system is starting up I got the following error

System uptime in nanoseconds: 643919837

Could you help me with this new issue?
