Legacy RAID BIOS Utilities: Select the Boot Virtual Drive

These are historical RAID BIOS interfaces. The shortcut alone does not uniquely identify a controller, so match the actual adapter and firmware manual. Selecting the controller boot drive does not install an OS or replace the server’s BIOS/UEFI boot order. Verify that the chosen virtual disk contains the intended bootable system.

1. Ctrl+H / MegaRAID WebBIOS

Open Virtual Drives and inspect Set Boot Drive. The first source capture shows current=NONE. The source says its system then falls back to VD0, but NONE itself only says no explicit boot virtual drive is selected; do not assume every controller/host has the same fallback.

Select VD0 → Set Boot Drive → Go, then verify the resulting current value:

The source next demonstrates selecting VD2; the setting reads current=2 although the list highlight is still on another row in the capture:

2. Ctrl+A / Adaptec Array Configuration Utility

Enter Manage Arrays and identify the intended boot array. The source example lists array00 and array01, then highlights array01 and uses Ctrl+B to swap it with the first array in the boot order:

The pictures show an in-progress Setting up boot Array message, not final OS boot confirmation. The source also describes returning to the utility to restore the original boot choice. Use the actual array identity, not just a number that can change with ordering.

3. Ctrl+R / Ctrl Mgmt

Use Ctrl+N to reach Ctrl Mgmt and choose the Boot device field. The two examples show VD0 at 500.000GB and VD1 at 558.406GB; they are different captured selections/configurations, not a resized disk:

Apply/save through the matching utility workflow and verify the selected drive and host boot entry. No save operation is represented as completed by this translation.

4. Ctrl+C / SAS BIOS Configuration Utility

In Adapter Properties, open SAS Topology, highlight the intended disk or RAID logical volume and use Alt+B to select it as the first boot device. The Device Info field then shows Boot:

Press Esc, then choose Save changes then exit this menu and press Enter in the confirmation dialog, as described by the source. Confirm the intended volume before saving.

5. Ctrl+M / LSI Software RAID utility

Choose Configure → Select Boot Drive, select the intended bootable virtual disk and press Enter. The source says successful saving displays Boot Drive Information Is Saved. Press Esc to return to the main configuration menu.

The source screenshot shows the list and current boot VD0, not the quoted success message. Confirm both controller and host boot configuration before a planned boot test; none of these actions has been executed here.
