legacy boot

I have an Intel NUC7PJYH and I need to install a 32bit OS in legacy mode. I contacted Intel support and an engineer informed me that a certain version of the BIOS removed support for UEFI and I could downgrade the BIOS to version 27 to get it back. So, I downloaded and downgraded my BIOS to version 27 and I still cannot detect any legacy boot devices. I have even tried to install the OS (Ubuntu 16.04.5 32bit) onto the drive in another machine and swap it in to see if it will at least see GRUB. No dice. It doesn't detect legacy devices at all.

Does anyone have any other ideas how I can get this done?

nivekxyz: I want to start off by stating that Intel removed support for Legacy, not UEFI, so there is no misunderstanding.

 

 

For this NUC, UEFI Boot is required to install Windows 10 64-bit. Which 32bit OS are you trying to install?

 

 

As far as Ubuntu, we have confirmation from Canonical that Ubuntu 16.04 LTS can be installed on this NUC.

We recommend reaching out to the Ubuntu forums for assistance in installing Ubuntu:

We also recommend that you confirm you are using supported hardware (i.e.: RAM) and components as this might affect the performance of the system:

If you are able to boot into an OS, we can always verify the components of your system if you provide the SSU report:

I see that you have a duplicate case already open with us. Do you want to continue on the forum support or on the initial case?

I am trying to get Roon OS onto my NUC7PJYH and it needs legacy boot. Can someone confirm that BIOS V27 actually still has the legacy boot option?

Hello rudolffischer

 

 

Thank you for posting in the Intel® community.

 

 

Allow me to share with you the on the BIOS 0037 release notes on the new fixes/features on the statements the Legacy Boot Priority pane from BIOS Setup was removed.

In this case, I would recommend testing the BIOS version 0027 to try the installation of Roon OS.

 

 

Hope this helps.

Thanks for the heads-up, Leonardo

I tried to downgrade to Bios 27, but I got an error message that the bios could not be downgraded. How do I go back to 27?

Hello rudolffischer

 

 

Thank you for the information.

 

 

Bear in mind that if the BIOS 0042 or grader is installed on the Intel® NUC completing downgrade would not be possible according to the release notes on the Bios version 0042.

Thanks, Leonardo
