Currently, the MBR on my machine is corrupted, so I decide to re-install GRUB from a liveCD and with
chroot. From this tutorial, I can complete the re-installation. However, I'm not clear about the reason why I should mount
/proc on the new root environment. (For
/sys I think it is because some files should be referred.) Is the same reason for
/proc, which files on
/proc are required when re-installing GRUB?
Thanks and Best Regards!
