I switched the secure boot on and added passwords. I tried a few things: I moved the HDD option to the top of the boot priority order menu. After installing Ubuntu, restarting, removing the USB key and letting the laptop power up again, I got a 'No bootable device' error. I went to the boot menu and changed the boot device order so that USB HD was in position 1, and then hit F10 to save the changes and restart. Anyway, it's an improvement over the Toshiba I'm writing this on, so I decided to install Ubuntu on the new (well, ex-PS4 - don't ask!) disk.Īfter creating a new bootable USB drive using Rufus, I inserted the USB stick into one of the Acer's ports, switched it on and repeatedly tapped F2 until the BIOS menu appeared. It originally had a 1Tb hard drive but that died, presumably after being carried around school for several years by my son, so that needed to be replaced. My latest acquisition is an Acer Aspire E5-532, with 8Gb RAM and a 500Gb hard drive. I'm the only software developer in my family, so obviously I get the best laptop! Well actually that's a lie, I tend to use whichever fancy laptop my employer provides me with for work, and for my personal projects I inherit whichever of the kids' laptops has been most recently replaced.
