Hi Everyone, I just dnf-upgraded my last system from F37 to F38. One of the post-upgrade task is "Update GRUB bootloader on BIOS systems" (https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/): Systems with the BIOS firmware have the GRUB RPM packages updated. However, the installed or embedded bootloader is never updated automatically. It is a good idea to update it between Fedora release versions. I have a system that is is using BIOS, and it not using UEFI or SecureBoot (though UEFI is available): $ sudo dmidecode | grep -i -E 'BIOS|UEFI' Getting SMBIOS data from sysfs. SMBIOS 3.0.0 present. BIOS Information BIOS is upgradeable BIOS shadowing is allowed BIOS ROM is socketed BIOS boot specification is supported UEFI is supported BIOS Revision: 1.0 $ mokutil --sb-state SecureBoot disabled Platform is in Setup Mode When I run the command: $ sudo mount | grep "/boot " /dev/mmcblk0p2 on /boot type ext4 (rw,relatime) Do I install grub2 on /dev/mmcblk0 or /dev/mmcblk0p2? I think it is the former, but I want to make sure. That is, is this correct: sudo grub2-install /dev/mmcblk0 (I have open questions about systems that claim both BIOS and UEFI, but I have not been able to find answers. If I need to back up a bit, then please say so). Thanks in advance.
