Network, mouse, BT not working after grub edit

In my dual boot menu Trisquel wasn't first and I wanted to change that so I edited grub via 'sudo nano /etc/default/grub' (and update-grub).

After reboot Trisquel doesn't recognise my wifi (network card), mouse, bluetooth and probably more.

Is there a solution to this problem or do I need to reinstall the OS?

Well, that is weird. There is no reason for a change in /etc/default/grub to make your hardware stop working. Don't you installed a kernel as well? You could try to boot an older kernel (you have not removed them all, right?) by choosing it in the "Advanced options" of the GRUB menu (press Shift right after the computer turns on to make this menu appear). You would be asked the GRUB password in /etc/grub.d/01_PASSWORD so either read it before (with 'sudo cat /etc/grub.d/01_PASSWORD') and remember it or, better, disable it (making all /etc/grub.d/01_PASSWORD's lines start with '#' and executing 'sudo update-grub'). You could try to update the kernel too: https://trisquel.info/en/wiki/update-linux-libre-kernel

I didn't install a kernel and I didn't remove anything but update-grub did remove some lines in the grub menu. These may have been older kernels but I'm not sure. I just installed Trisquel some days ago, so I wonder if there should have been an automatic kernel update this soon?

In the grub menu I automatically get the option to choose 'Advanced options for Trisquel GNU/Linux' but entering them leads me back to the grub menu.

Actually I had the same issue when I first installed Trisquel. I fixed with a clean install.

Thank. Updating the kernel did the trick. I still have no idea what happened in the first place though!
