Why is my computer asking me to choose a boot order?

Episode 1274 (1:46:30)

Fran from Sherman Oaks, CA

Fran updated to Windows 8.1 and now she has to always choose a boot loader. Leo says that could point to a stuck F12 key. But it could also point to a changed boot order in BIOS. She should change it back to boot Windows first. Leo also suspects that the motherboard battery is dying. It can easily be replaced by popping it out. If her date isn't correct, then she'll know for sure.
