Help! My Acer Laptop Says ‘No Bootable Device’

First things first, try entering the BIOS setup. You can usually do this by hitting a specific key (like F2 or Delete) when you power it on. Once you're in there, check if your system drive is listed. If it’s missing, then the hard drive might be dead and you should consider getting a replacement. If it is there, make sure it’s set as the first boot device. If everything looks good but it still won’t boot, you may need to reinstall Windows using a USB drive.

To set your drive as the first boot device, go into BIOS and navigate to the boot menu. You should see the option to move devices around. Typically, you can use the arrow keys to select your drive and then change the boot order. If you need more help navigating, just ask!
