I have been attempting to Enable Legacy boot and Disable Secure boot on this machine for a few days now. My current BIOS version is N01 2.05 11/11/2015. It is the oddest thing. I am able to make some changes, save and have them succesfully change...but I cannot get legacy to enable and save. Steps I have taken:
- Cleared Secure Boot Keys - Reset
- Selected Legacy Support Enable and Secure Boot Disable - Reset
- Go back to BIOS --> Boot Options -->Attempt to Uncheck UEFI Boot Order (Unable to) --> Check to see if Legacy Boot is available and its a no go
- Then I go back to the secure boot options and verify that none of my changes saved.
I have tried rolling the Bios Version back to 2.04 but that didn't make any difference so I put 2.05 back on it.
I am attempting to get these machines to PXE boot to grab our school district's image, but I need Legacy boot enabled to do it. After several attempts to get Legacy to enable I resolved to just use our Win7 Ent disk BUT can't do that as well as it says the "selected boot image did not authenticate." Of course the fix I found for this was enable Legacy Boot....which I can't do.
I have looked through the forums and found a few possible solutions, but none of them have worked. Please help!
