How can I dual boot in a UEFI secure boot laptop?

Episode 1045 (51:09)

Sterling from Nina, WI

Sterling bought a new Acer Aspire M5 laptop that has Windows 8.1 and UEFI, but he can't install Ubuntu to dual boot it. Leo says that if he goes into the settings for the UEFI firmware, he can set it up. But it's not trivial, and it's not supposed to be. The BIOS can be modified to reinfect a computer, so UEFI was designed to combat that. It also causes dual boot computers to not work in that configuration. Leo was able to do it by disabling secure boot.

The chatroom also says to change it back to "Legacy." He can also try booting from a USB key. If that doesn't work, there could be driver incompatibility. Leo advises searching the net for it. The chatroom says that some Linux distributions are UEFI certified. Here's a technote that may help.
