# mount /boot
# grub-install --recheck --no-floppy /dev/sda
Generate grub.cfg
Warning: Running the following command will overwrite any changes in grub.cfg you manually made.
# grub-mkconfig -o /boot/grub/grub.cfg
Configuration
Note: Manual grub2 configuration should always happen in /etc/default/grub and/or /etc/grub.d/40_custom.
Optional: Additional Kernel Parameters
File: /etc/default/grub
GRUB_CMDLINE_LINUX="acpi=off"
Regenerate your grub.cfg for the changes to take effect.
Optional: Theme
File: /etc/default/grub
GRUB_THEME=/boot/efi/EFI/grub/themes/starfield/theme.txt GRUB_TERMINAL_OUTPUT=gfxterm
If your display resolutions isn't automatically detected you can manually force a specific resolution.
File: /etc/default/grub
GRUB_GFXMODE=1600x1200
Regenerate your grub.cfg for the changes to take effect.
Optional: Serial Console
File: /etc/default/grub
GRUB_TERMINAL=serial GRUB_SERIAL=COMMAND="serial --unit=0 --speed=57600 --word=8 --parity=no --stop=1" GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,57600"
Regenerate your grub.cfg for the changes to take effect.
If you want to be able to login to your system via the serial console you need to edit /etc/inittab.
File: /etc/inittab
