What command does the installer use to install the boot loader?
I sucessfully installed CentOS 8 to the server, with /usr on a mirrored SSD pair on the RAID controller and /boot on the internal SD card (where Dell wants one to boot from). Before rebooting, I inspected the installation at /mnt/sysimage and the disk usage looked reasonable. I saw a grub directory in /boot but no second stage boot loader nor any config files for it.
At the end of the process, I got an error message that the installer failed to install the boot loader and the resulting system wouldn't boot. It didn't. There were no details useful for diagnosis. So now I'm about to boot the installer DVD into rescue mode to manually install the boot loader and see the real error message. So what command do I issue?
