Ya ... same problem. When booting on lenovo s510p the boot loader doesn't even show up.
Tried making different bootable pendrives from Niresh DMG and ISO versions as detailed in the guides.
The pendrive works flawlessly on other laptops i.e. my Asus K53SD , installed and working fine.
But when booting on Lenovo S510p , the bootloader doesn't even show up giving up a black screen.
I am not able to reach the Niresh's Mavericks boot screen.
Also tried with different bios settings ... like changing UEFI and Secure boot... etc.
Please HELP .!
