My PC boot option, that is pre grub menu list loading, suddenly change unnoticed
At bottom left it echos message kinda:
"Press ESC for startup option"
(previous one is nothing at all)
and worse is, now it cannot detect a present USB drive from which it should automatically boot
although did press ESC, pick BIOS setup and pick Boot Order, moving up and prioritizing kinda: " USB CD/DVD ROM drive "
it still ignore the present USB drive
Anyone know solution ?
EDIT
moving up and prioritizing the line, kind of: " USB diskette CD drive "
has solved it !
But no idea what caused sudden change in boot order so "OS mainstorage" is on top
I had this happen sometimes on proprietary uefi systems, but for a more standard one it's unusual, so for posterity which system are we talking about?
