FortiManager VM deployment Issue

Hi, i tried to deploy FortiManager following this doc: https://docs.fortinet.com/document/fortimanager-private-cloud/8.0.0/microsoft-hyper-v-administration-guide/449452/creating-the-virtual-machine

Added a second Hard Disk in “IDE 0”

Show me this error, i tried to create Fixed and Dynamically (in differents clear installations) but same error appears even when i have enough space.

After this error i cant type in terminal. Any suggestion?
