Trying to install Mageia 3 to LVM

Hello all,
Im a trying to install Mageia 3 to a logical partition of an LVM. By custom, I use the full DVD Mageia-3-x86_64-DVD.iso. Is it possible at all with this installer? I missed the option to choose between grub Legacy and Grub2, and where to install the Bootloader. I dumped to ISO to a pen drive (command dd). I put everything into one partition, no separate /boot or /home.
The installation runs to a point after configuring root and user
Preparing bootloader ...
Internal error sdb10 ... unknown device ...
There is no sdb10 on my hard drive.
Best regards,
Bequimão
