I am using an apc4100 (UEFI Boot) and installed the Hypervisor via USB. AR is working fine and it is also functioning well as a PLC, but when I checked the partitions in Disk Management, they are not partitioned and remain as Unallocated. Why is that?

I installed it by referring to the link below. The installation was done under the AS6 environment.

Hello,  
i am not an Expert on Hypervisor, but i try to understand your request…

As far as i understood you are not seeing the same situation like shown in AS-Help for the Partions after installing Hypervisor.

[Partions for Hypervisor shown in GPOS](https://help.br-automation.com/#/en/6/automationruntime/targets/hypervisor/gposinstallieren.html)

- Did you do a full restart of the whole system?
- Which image of partitions do you get?

Greetings  
Michael

Hello,  
I think i should have read the help more in detail. Could this sentence be the solution?

Thank you! I think this explanation is correct. So it is normal that the partitions are not visible.
