Problems installing grub, what to do?

Question

linux

Good afternoon. I'm having a problem with grub, I'm trying to install grub on dev/sda2 and the installation goes without error. But after I turn off the live distribution and try to boot - the computer does not start grub. Here is the disk information.

Here is what I write in the console

[email protected]:~$ sudo mount /dev/sda2
[email protected]:~$ sudo grub-install  --boot-directory=/mnt /dev/sda

Installation for the i386-pc platform is in progress.
Installation completed. There are no errors.

Nothing works after that, please help.

Answer 1

When installing, create such a partition and register in it, EMNIP.
