Issue
On 13G PowerEdge Servers, when trying to install the Operating System using legacy BIOS with 4K Sector Physical Disk (Size of sector) , the bootable Virtual Disk disappears.
Resolution
- Using BIOS boot mode, remove all Virtual Disks.
Warning: Remove a Virtual Disk will delete all data on this VD.
- Switch the server boot mode to UEFI and start into the Life cycle controller.
- Create a new Virtual Disk from here and proceed with the Operating System installation.
Also, this is required that the Operating System supports UEFI boot mode. you need to ensure that the OS supports the same settings.
