sudo update-grub

or fix it with Boot-repair (no use)

sudo add-apt-repository ppa: Yannubuntu/bootboot-repair

4, if the system does not start properly, then you need to go into the live CD, then mount the new hard disk partition, and then update the grub, such as the following actions

#/dev/sdb1/mnt#/dev/mnt//proc/mnt//sys/mnt/sys# Finally switch root root directory to//mnt# execute update-grub to update boot sudo update-grub

#/mnt//mnt//mnt//mnt
