Debian Installer can create MDADM RAID volumes even in non-expert mode.

You need to explicitly select the right options in the installer  
partitioning screen i.e. create the partitions, then create MDADM RAID 1  
devices on top of them and finally let them be formatted with  
ext4/filesystem of choice and be the installation target.

AFAIK "Guided" installation modes do not automatically create RAID, i.e. I  
recommend using the manual partitioning mode.

In the few RAID installs I did, it worked out all of the time.

Only thing to do afterwards is to ensure that GRUB is installed on both of  
the respective devices (dpkg-reconfigure grub-pc assuming BIOS mode).
