I currently have an Acer Swift 3 SF315-52 Laptop. I restarted the computer to fix an application bug, but when I tried to boot it up, it gave me a “No Bootable Device” Error. I looked into possible fix’s on the internet and most of them recommend changing the Boot Mode from UEFI to Legacy. However, this option is grayed out for me and I cannot change it. I have attempted to change many other settings in the bios to change the boot mode, but I have still not figured it out.
To fix this I contact nathan, he was able to fix this issue under the geek squad protection plan. I highly prefer such protection or insurance plan for your devices. As they come very handy in such situations.
