allowLegacyCPU=true when installing - get error: "No persistent storage available for system logs and data. ESXi is operating with limited system storage space. Logs and system data will be lost on reboot"

Hello,

I am trying to install VMware vSphere Hypervisor v.7.0.0. 15843807 in a HP DL380G7 with 2 x XEON E5645 2.40GHz

In my first attempt I get the error: "CPU is not supported by ESXi 7.0.0"

In order to by-pass it I enter (SHIFT-O) the parameter: allowLegacyCPU=true

Now I get the error: "No persistent storage available for system locks and data. ESXi is operating with limited system storage space. Logs and system data will be lost on reboot"

Any ideas?

Thank you very much for your kind time and support

With my warmest regards for all of us
