Repairing Fedora Grub using Fedora Live USB

First, Prepare the Fedora Workstation Live CD using Fedora Media Writer.

Next, run the Workstation Live CD and run the console.

Then, enter the following commands if you are running the separate boot and root partition:

1) sudo mount /dev/sdaX /mnt

Note: sdaX is the root partition

2) sudo mount /dev/sdaW /mnt/boot

Note: sdaW is the boot partition

The following files are essential for running the essential processes for repairing grub and shall be mounted:

3) sudo mount --bind /dev /mnt/dev

4) sudo mount --bind /proc /mnt/proc

5) sudo mount --bind /sys /mnt/sys

6) sudo mount --bind /var/run /mnt/var/run

Now, you are ready to go into the Fedora partitions to repair the grub files. The path should be changed to root user from liveuser> to root>:

7) sudo chroot /mnt

If you are running dual boot Windows and Fedora system, the following command will replace the Metro Interface:

8) grub2-install /dev/sda

With a dual-boot or multi-boot systems, the following command probe for operating systems installed on your harddrive:

9) grub2-mkconfig -o /boot/grub/grub.cfg

Now, we should be done with the repair and can proceed to unmount the boot and root partitions and other files.

10) exit

11) sudo umount /mnt/var/run

12) sudo umount /mnt/sys

13) sudo umount /mnt/proc

14) sudo umount /mnt/dev

15) sudo umount /mnt/boot

16) sudo umount /mnt

Finally, we can shutdown and restart to see if it is successful. Sometimes if there is any error message along the way, we need to run this process twice.

Fixing time on sysvinit and systemd

If you have a system that boot using different GNU/Linux init systems such as sysvinit (aka System 5) and systemd (aka System 500) in addition to proprietary Windows system, you may face incorrect time display on one of the aforementioned system. The difference in time display is dependent on the time difference of your location and the UTC time. Further complication may result from concept like Daylight Saving Time (DST). If the Bios is set to localtime, you may fix it in systemd boot system using 'timedatectl' command like: sudo timedatectl set-local-rtc 1 However, if you are using sysvinit and Bios is using localtime, you can set inform the system that local time is being used using 'hwclock' command like: sudo hwclock --localtime or to synchronize the hardware clock with system time and inform the system using: sudo hwclock --systohc --localtime If Bios is using UTC time, you may revert the change with 'timedatectl' like: sudo timedatectl set-lo
