Yes, I read your manual very carefully. I will do so. We simply replace the contents of the file and all date attributes are correctly saved. I just don't understand why this happens with dates... When updating from 14.1 to 14.2, it would have been more logical to throw in a file with a new date bootx64.efi so it turns out that on 14.1 there was a loader.efi, if the update brought a new loader.efi, and about bootx64.efi they kind of forgot... I can't figure it out.
Okay, I'll read the manuals in more detail. Thanks A Lot, Emrion!
