you might have to downgrade your bios to A03 then Back to A012. because of graphics glich.

How? I tried searching it yesterday but got no luck. 


EDIT: I found the correct page i think. Which of these would work the best?














EDIT: I updated A12, i searched some other examples and then just chose that one. Does that work?

0xAAt3D.jpgAfter i created the usb stick it just boots here. When i press continue it just comes back to this screen. What package must i download and do i have to follow UEFI or Legacy. Then when i was in the stage where i had to move the E6430 kexts and other to EFI partition it didn't had similar files. It had EFI folder where it had the files that suppose to replace. Hope for help! Thanks alot! :)

Did the BIOS update again how you said. Now i am doing the UEFI boot installer. Everything else is easy i think, but i didn't understand this stage.




Do i have to transfer the files in E6430 to the root of the EFI partition or to the EFI folder and do i delete the EFI folder after that?
