I went fiddling into the BIOS 2.14.1219 of my Asus UX31A laptop, wanting to enable network booting, to give it a test ride. Except I did not fiddle with even one setting, as the BIOS boot menu was plain lacking items. The items were not grayed out, they were not into a zone of the screen I forgot to check, as I triple-read each word from top-left to bottom-right, they were not just there,
in particular there was the classic
"Delete Boot Menu Item" - but its essential companion "Add Boot Menu Item" wasn't there.
I checked and triple-checked the security menu, no passwords are set. No one ever uses my computer, and no proficient computer user that knows what a BIOS and would perversely want to hack my computer for their own dark designs ever enters my home, only computer-illiterates.
Still it seems highly unlikely that a BIOS got corrupted in a way that yet permits complete and functional use of the computer. So what did I forget to triple-check?
Thanks a lot, this is perplexing!
