Hope someone can help! Daughter has an Acer One 14" 431 Cloudbook. This has a 32GB SSD, and using the usual update route, the installer says not enough space, required 20GB (understandably). Thought I could reinstall via standard USB process, but the laptop will not boot from standard USB, only UEFI, and is formatted with GPT, and will not boot from a legacy USB stick. Thought I was clever, and exported allof the drivers via Powershell, deleted all of the partitions, was then able to boot from USB and install W10 Anni from USB. Everything worked fine, except the touchpad, which does not work at all, and there are 4 entries in device manager where the drivers are not installed, and not of the exported drivers, or the drivers from the Acer website, will help. Now restored the original disk (took an image of it first). Any ideas how I can perform an upgrade of W10 to Anni (which presumably will resolve the driver/ touchpad issue)?
