First letter on this forum so Hello!

I`m fighting with Kali for last week. I`m depressed and disappointed. I was reading ton of posts but at the end nothing. My HW system is complicated and I don't even know if it is possible
to run this set up with KALI.
SDA & SDB running in hardware Raid0 there is also sdd (miniPCI) disk
I would prefer to install it on HDD and keep the Bios Raid0. Any chance?
On Raid HDD I have windows7 Pro (64x), W8.1(64x) . On SDD 8.1(x64).

I have problem with installing grub!
TO my knowledge I can not install it on raid0 only raid1. I was trying to install kali on SDD but again SDA for grub is not available.
Please help.
My Linux knowledge is less than basic. I will provide all info just give me the command please....
I can run Kali live.

Thank you for your understanding!
Fishman.
