Editing of BIOS and UEFI boot order
- failing PXE boot as in this thread
- on UEFI systems, Windows puts its own boot file on GPT partitions on first place in boot order after first startup; after that the machine looses ability to non-interactively boot to PXE if the need occurs (for now I'm using EasyUEFI script to rectify it)
It could work via Toec and as an option in PXE script, too.

The LIE already uses efibootmgr to set the boot order. It should keep your boot order the same. You can verify in your imaging log. It will show you the boot order before imaging occurred and the boot order.
The WIE doesn't really have any reason to modify. You can't keep PXE as the default option when using the WIE. You can only PXE when you want to image.
