Opensuse Rescue System Reinstall Grub In Ubuntu

I recently repartitioned my HDD and I have damaged GRUB on my system. On boot I get the GRUB rescue prompt and I have to go through the following steps in order to boot normally:

Get a Live USB stick. I will prefer Ubuntu Live USB stick. Open terminal after booting up into the live desktop. Mount the root partition by typing /mnt and boot to /mnt/boot and hit enter. Sudo grub-install --root-directory=/mnt --boot-directory=/mnt/boot /dev/sda] You.

1. If you are interested in MiniTool Partition Wizard Bootable Edition, just purchase it's Professional Edition to create a bootable disc to boot your computer and fix no such partition grub rescue in Windows 10 now.
2. Repairing a broken Grub 2 bootloader: There are tons of us here who broke their grub thanks to autoupdates through apt or similar. Hopefully, this will allow them an way to fix their system without reinstall. Grub now features an advanced rescue mode, truly a godsend for people who somehow messed their MBR tables up.

(Those steps were found on another post on here!).

I'm very tired of repeating this on every boot, how do I permanently fix GRUB?

• Now just fix grub by following command on any Ubuntu

make sure you must update grub after login into OS

I would try running update-grub in order to build grub.conf / grub.cfg again.

You can try also using grub-install, but I think this one won't help.

If you want to read more, check first which version you have (GRUB 1 or 2) by running:

If you have GRUB 2, you can use the following tutorial: http://www.dedoimedo.com/computers/grub-2.html

Of course be careful dealing with GRUB as we are talking about the boot process, which is a sensitive mechanism.

It seems to me that update-grub assembles the grub.cfg, but you also need to (re-)run grub-install (or grub-setup?) to update the MBR / boot sectors with the basic info -- on which partition to find the grub.cfg http://waycebatin1983.mystrikingly.com/blog/. file & apparently these modules.

When you get a GRUB rescue prompt, it means that the GRUB bootloader cannot locate its modules from the partition that contains them in /boot/grub. The reason for this is that the code that fits in the drive MBR record is tiny, and so its main purpose is to locate and load the rest of the bootloader code. Once it's loaded its modules it can present the GRUB menu and handle the rest of the boot process. If it can't find the modules, it presents a very limited rescue prompt.

So, what you are seeing is totally normal if you repartitioned, thereby breaking the reference the bootloader had to the partition containing the boot modules.

Since you can boot manually, the simplest fix is to manually boot and reinstall the bootloader in the MBR so that it has the correct reference to your partition. The way to do that is:

This assumes you boot from /dev/sda (most cases, but if not, replace it with the correct drive).

This solution is far simpler than using the boot-repair, but if you are unsure this may be more suitable.
