Hello,

I'm a lazy Linux user who doesn't know much, so bare with me. I have some serious problems that I don't know how to solve, so I ask for your help. Trying to learn as I go.

On my ThinkPad T450s on which MX Linux 21 is installed, I'm stuck after a reboot on a page saying the following:
GRUB loading
Welcome to GRUB!

error: symbol 'grub_disk_native_sectors' not found
grub rescue>

I have absolutely no idea what to do and haven't been able to find an answer elsewhere. This happened after a recent update in MX Linux where something concerning GRUB didn't install properly.

Thanks in advance!

If you can get a terminal open then try

sudo grub-install /dev/sda ; sudo update-grub

Thanks for the quick response! I'm all stuck on the GRUB page, can't get past it, no terminal available : (

I tried to follow the steps in this guide: https://phoenixnap.com/kb/grub-rescue
It went fine until I wrote the "insmod normal" command, and got the answer: "'grub_disk_native_sectors' not found."

Go to the page I mentioned in my above post.
you may have to enter a search in the menu for boot-repair. It works on my t450 here no problem.
Uses the live session usb to do the repair and should work for you also.
boot-repair is now found under mx-tools section.
(Note: remember the password on the live session is (demo)

It doesn't look good... I made bootable USB memory with MX Linux 21 and when I choose it this text appears:
error: no such device

UUID Error!
CAnnot find partition with uuid: c8fa7d58-f279-458e-a050-1d1bbadad186

Searchingpartitions for fallback file
/boot/grub/config/19678c5067c1376ecf2f58f69d5bd50b.id
Then I have a countdown for 99 secconds before it says "giving up". After that I'm back on square one on the GRUB page.

I've tried the USB in all 3 slots with the same result.

So it won't even let you boot to the USB?
Almost sounds like the HD has bit the dust.

how did you burn the USB? I suggest you download Etcher and use it. It is cross platform and will work on windows as well as linux.
Make sure you have your bios set to boot from USB first. Even if the HD is gone it should still boot to the USB.

Make a new Bootable USB as per @kc1di instructions - then
1)Boot the installer in rescue mode.
2)Select the root device.
3)Reinstall GRUB in the proper location.
4)Reboot and select the proper boot location for future grub* package upgrades with
Code:
dpkg-reconfigure grub-pc
or
Code:
dpkg-reconfigure grub-efi-amd64

depending on BIOS or UEFI mode

I'm using the command line, following this guide: https://linuxize.com/post/how-to-create-a-bootable-linux-usb-drive/
It has always worked fine before. But I'll try it with Etcher too and give it a go!

Yes, I press f12 when rebooting and then I choose to boot the USB from BIOS. It does register the USB correctly there, but in the next step something goes wrong.

It's weird because I made the update that went wrong about a week ago and didn't reboot my computer for that whole week. I've been using my computer daily with no problem. It was today when I rebooted it that this happened.

Thank you all so much, you saved my day! It worked with Etcher, that's probably more reliable than the command line option I used. I followed your steps and hit the goal, gained some knowledge too.
