System Won't Boot Back to a RAID Volume






  • Replaced a failed hard drive, and now the system will not boot to the RAID volume.
  • I installed a bootable device.
  • The system does not boot after a Raid Array configuration is done.


To resolve this issue, check the priority of the RAID volume in the system BIOS setting related to boot order.


 If the initial RAID set-up was created from within the RAID controller BIOS, make sure the Boot Mode in the board is set to Legacy, not UEFI.  

Some system BIOS will give the newly inserted hard drive higher priority in the boot order than the degraded RAID volume and will subsequently attempt to boot to the newly inserted hard drive instead of to the RAID volume.



 The instructions below are specific to motherboards manufactured by Intel. Always follow the instructions that are provided with your motherboard. The specific instructions on non-Intel manufactured motherboards may differ. 

  1. Press F2 after the power-on self-test (POST) memory test begins to enter the BIOS setup menu.
  2. Click the Boot menu, and then the Boot Device Priority menu. On the newest Intel server boards, the Menu option is called Change Boot Order under the Boot Maintenance Manager = sub-menu. See Intel® Server System BIOS Setup Utility Guide for more information.
  3. Using the up or down arrow keys, select the RAID volume as a boot device.
  4. Press F10 to save the setting and exit the BIOS setup program. The system should now boot to the RAID volume.
