I have Intel Raid Controller as well [1]. My experience is as follows:
1) Automatic preseeding with installer booted in BIOS (Legacy) mode, ends up installing grub into /dev/sda, succeeds unattended and fails to reboot.
2) Automatic preseeding with installer booted in UEFI mode, succeeds unattended and successfully reboots into a working system.
Does the machine in question can boot in UEFI mode?
I also wonder how similar raid controller in the affected machine is similar to mine [1] (Z77 intel south bridge)
