Hello All
Fresh guy here (First try BSD, just want some this true UNIX feel), but I got one problem.
I got Lenovo Y70. I install FreeBSD from usb, all go nice and smooth ,making a 3 partitions (auto from Bsd installer) swap, boot, and /.
I am using Grub 2 to boot BSD , i got grub installed on EFI disk from windows.
menuentry "FreeBSD" --class freebsd --class bsd --class os {
 insmod ufs2
 insmod bsd
 set root=(hd1,7)
 kfreebsd /boot/kernel/kernel
 kfreebsd_loadenv /boot/device.hints
 set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ada0s1a
 set kFreeBSD.vfs.root.mountfrom.options=rw
 set kFreeBSD.hw.psm.synaptics_support=1

It's booting ok unless i just got weird graphic scramble( and think that it's even working, pressing enter just reboot it again to grub)

My specification is a
  1. Intel HD Graphics 4600 and Nvidia GeForce GTX 860M.
If i just run Live CD from usb it boot normal, I can even mount my partition system, but can't make any ports (just try to install Nvidia drivers), i just a problem with wifi too, but this is just another story, for now i just need to make it boot just from Grub2.
Solved. It was easy like hell, If you got same problem. I just use disk
1. Make normal Free bsd instalation ,
2. Instal grub2 on your Efi partition (if you don't have any, find how to make one )
3. Copy all stuff from FreeBSD Efi to /EFI/FreeBsd
4. Add in Grub.conf
menuentry 'FreeBSD 11' 
    set root='hd0,gpt2' // Your EFI partition
    chainloader /EFI/FreeBSD/BOOTX64.EFI
