I can run via rescue mode
then
Quote:
sh-4.2# chroot /mnt/sysimage/
Quote:
sh-4.2# /sbin/grub2-install /dev/sda
then try to reboot but getting error
running in chroot ignoring request.

What can I do

It would help to include the error message...

Which directory did you delete, /boot/grub2?

The OP needs to reinstall the grub package first versus re-installing the boot loader code.

yum reinstall grub2
