Trisquel won't run on any of the ARM-based (e.g. Exynos, NVIDIA) Chromebooks as it is x86-only.
I believe you might have to change the BIOS settings to use "Developer Mode" in order to delete Chrome OS and install Trisquel on the Chromebook. There is a thread from last year on the Acer C7 model specifically: https://trisquel.info/en/forum/acer-c7-chromebook-updates Muhammed just posted a wiki page which might be worth reading/watching for updates: https://trisquel.info/en/wiki/chromebook Search might help as well: https://trisquel.info/en/search/node/chromebook Andrew
