Error loading boot media

Hi to the list,
i have problems with my Raid5 and had to deleted and recreated it.
After recreated it i've tried to boot the pc with the ATI 2012 boot disk
but while loading i get the following error:

Acronis True Image Home has detected unsupported
hard disk drives. Acronis True Image Home does not
support Windows Dynamic Disks, EZ-Drives, etc.

I cannot do anything because when i click on the OK tab,
the PC resets.
Please how to avoid the problem ?
Thanks in advance.
