Zorin os freezing while installing.
 

Hi I was trying to install zorin lite 15.3 and after clicking erase disk it successfully copied files, but when installing it was freezed in Running "grub-install /dev/sda"..
How can I fix it?

Search on "grub chroot install". Then follow the instructions for doing it when you boot the Zorin installer, from a shell when booted with it. Hopefully it is not total junk and will get it done using it, though I doubt I would bother as it failing to do it from the installer would make me think it was piece of garbage to start with. After all that is the function of the installer to give you a working system once used, if you cannot get that right what else is wrong in it.
