To resolve this issue the iDRAC firmware and BIOS need to be updated.  In the case of a Windows installation it may also be required to perform a rebuild of the BCD (Boot Configuration Data) store.  Below are two methods to perform the updates.

  1. Boot the server to the OMSA Live CD.  The OMSA Live CD can be found here <>
  2. Boot the server to the LCC from the F11 boot menu at POST.

Additionally if Windows still will not boot after updating iDRAC and BIOS perform the following steps.

  1. Boot the server to the Windows DVD
  2. On the language and keyboard settings page click Next.
  3. Choose Repair your computer.
  4. Install drivers as needed.
  5. On the System Recover Options page choose Command Prompt.
  6. At the command prompt run the following command: bootrec /rebuildbcd
  7. Upon success, press Y to accept the changes.
  8. Reboot the server normally.

Additional Information:

This issue occurs due to a mismatch between the software (LCC) and the hardware versions (iDRAC). 

To prevent this issue updates should be performed in the following order:

  1. iDRAC
  2. LCC
  3. BIOS
