13.04 install failed on intel's fake RAID5. Bootloader could not install

[GoranP]

Raid is recognized ans system is copied but bootloader could not be installed. It requieres /dev/sda that does not exists.

You need to choose manual partitioning and make sure to select the raid array ( /dev/mapper/isw_dhacdhbfcb_main ) instead of /dev/sda for where to install grub. Also if you are not dual booting with Windows, it is best to avoid fake raids and use conventional linux software raid instead as it is better supported.
