Unable to install Grub (RAID0 software)

[division]

Hello everyone,
Sorry for my bad english, I will try to do my best to explain my problem.
I have try to install debian in a new computer (old computer with 2 new HDD).

Config : Asus rampage III/ i7 / 6go Ram / 2x 3To HDD.

So, I have made my RAID0 with the debian installer for my 2HDD (it's not a dual boot) and at the end of instalation, when the installer tell me where install GRUB,every path generate a fatal error. And when i finish the install without boot loader, i can't start the OS.

Thanks for your answer.

Are you booting via EFI or legacy (MBR)?

The bios are on legacy, he dont have the UEFI option i think.

I have try every partition I have made so :

'/dev/sdb' -> 1st hdd
'/dev/sdc' -> 2nd hdd
'/dev/sdb1' -> 1st part of 1st hdd
'/dev/sdc1' -> 1st part of 2nd hdd
'/dev/sdb2' -> 2nd part of 1st hdd
'/dev/sdc2' -> 2nd part of 2nd hdd
'/dev/md0' -> the RAID0
'/dev/md0p1' -> the part where the grub is spec in the raid.
