Dell Technologies Server Troubleshooting Guide

No boot device found error message is displayed

Description—After the server completes the Power On Self-Test (POST) phase, the server is unable to boot a bootable device. This condition is called No Boot. Files available in a bootable device—RAID, USB key, DVD, or ISO file—contain instructions to start the operating system. When these files cannot be located, an error message—No boot device found—is displayed. You may observe this issue if the virtual disks are not online, due to a hard drive or PowerEdge RAID Controller (PERC) issue.

1. Check the hard drive status in the PERC BIOS.
   An error message—No boot device found—is displayed.
2. Press Ctrl + R during the POST process to open the PERC BIOS Configuration Utility.
3. To check if the hard drive is part of the RAID array, do the following:
   1. Press Ctrl + N to navigate to the PD Mgmt (Physical Disk Management) screen.
   2. Check if any hard drives are offline or missing.

      Table 1. Hard drive statusThe table describes the hard drive status

      Hard drive status	Description
      Offline	Hard drive is not part of the RAID array.
      Online	Hard drive is part of the RAID array
      Ready	Hard dive is ready to be a part of the RAID array

   3. Check that the Virtual Disk is online in an optimal state.
4. Click the CTRL Mgmt tab, and select the Virtual Drive where the operating system is installed.
   When the RAID is managing multiple Virtual Drive, it is important to select which Virtual Drive has to be presented when the server tries to boot on the raid controller.
5. If the problem persists, call Dell Technical Support for further assistance.
