Hi, you can try to deploy via LCC. But first I recommend the update OS driver pack. [URL] or you can try Windows Server 2019 64bit driver for PERC S150 ControllerRESTART REQUIRED [URL] Deploying an Operating System using Lifecycle Controller – Manual Install method [URL] Install Windows Server 2019 in UEFI Mode Using Lifecycle Controller on PowerEdge Servers [URL]  
I have a Dell PowerEdge R250 server with a 2TB HDD.When I try to install the Windows 2019 operating system it tells me that it cannot find any disks and that drivers are needed.I tried setting SATA AHCI in the BIOS and it doesn't see it, I tried setting RAID and then going to the S150 controller configuration and creating a virtual disk but nothing to do.I logged in via IDRAC and made the updates but nothing to do, I can't install the operating system as it doesn't see any disks. I don't know what else I could do to fix the problem, I tried them all. Even though I know something is missing How can I fix? thank you very much
