Changing UEFI Boot Sequence
Greetings. I attempted to search for my question but I didn't have much luck.
I have a PowerEdge R7525, and it is booting in UEFI mode. I would like to configure this server so that PXE is the first boot device attempted, followed by the local hard drives. I can change this in the "UEFI Boot Sequence" menu, and it works once, but after booting, it always changes back to "hard drive first."
I saw this comment in one of the Dell hardware guides:
> Changing the drive boot sequence is only supported in BIOS boot mode.
Does this mean that it is not possible to do what I want, to change the UEFI Boot Sequence permanently? Or is there another setting somewhere that I am missing?
Thank you very much.

I'm not sure I understand what you're saying. First you say it's not supported, and then you tell me where to fix it.
I can enable / disable the devices I do / don't need, but I cannot reorder them. Is enable / disable the only option I have?

Hello,
Yes I put the information to try to re-order them to see if you could try and verify if it will stick or not.
That would affirm that enable/disable would be the only option to ensure the PXE device you want to be the boot device.
I'm sorry for the confusion.

Hello,
It is noted: Changing the drive boot sequence is only supported in BIOS boot mode.

You can take a look in the System BIOS Settings > Boot Settings > UEFI Boot Settings.
Try to set UEFI Boot Sequence there or you can disable all options except PXE boot device you want to use.
