Troubleshooting

Cannot boot devices in UEFI Mode

Symptom
You see a message that the option or device you want to boot cannot be found, or it is listed in the system
configuration as an unknown device.
Solution 1
Cause
You are attempting to boot to an option that does not have a UEFI Option ROM driver.
Action
1. Verify that your option card has a UEFI option driver (Option ROM) that supports either x64 or EFI Byte
Code for boot functionality.
NOTE:
• UEFI drivers do not display messages on the System Utilities screen or provide function key prompts.
• If you replace the motherboard, UEFI variables are lost.
• You must configure PXE servers with a boot image. For x64 EFI machines, you must also configure the
DHCP server to support x64 EFI DHCP boot requests. For more information, see the UEFI Information

Solution 2
Cause
You are attempting to boot to an option that is not supported or is not running the latest firmware.
Action
1. Refer to the Quick Specs or Read This First card for your server to make sure that your card is supported
before you install it. Although third-party UEFI cards might work, they are not optimized for servers running
UEFI System Utilities.
2. Verify that the correct information is listed in the System Health settings for the option.
3. If necessary, use the latest SPP in offline mode to upgrade the firmware to the latest version.
Solution 3
Cause
You are booting Microsoft Windows 2008 R2, and UEFI Optimized Boot is enabled.
