How to fix "grub-install: command not found" error?

Question

linux

Friends, I ask for advice. The server is on Centos 7. Now we replaced the disk in RAID1, created a partition, added it to the system
. On prescribing the bootloader, the system issues the following:
grub-install /dev/sda
-bash: grub-install: command not found
What does this mean and how to solve it? Thanks in advance.

Answer 1

This means that the system could not find the grub-install executable in the paths specified in $PATH
Try which grub-install.
On Ubuntu it is in /usr/sbin/grub-install
It is also possible that you should be using grub2-install.
CentOS is not at hand, there is nothing to check on.
