Good day. i've been trying to boot my usb but i can't do it. it says "system doesn't have any usb boot option" message. what should i do?. So i have bought an acer aspire e15 for school at the beginning of the year but the thing is i want to boot to a linux usb. this is no problem with booting in legacy mode but i want to boot into uefi mode to see if it would make a difference since the linux distro i'm using doesn't display correctly.. Solved my acer aspire says default boot device missing or boot failed message, i press ok and ot sends me to a boot option menu with solution solved getting into boot menu in acer aspire e1-571g.
