grub rescue problem

Post by handyman4848 »

I managed to screw up my grub2 installation when I deleted a couple of partitions and now I get the grub rescue prompt on boot-up.

My Linux installation is on sda6.

From the grub rescue prompt I issued the following commands;
set root=(hd0,gpt6)
set prefix=(hd0,gpt6)/boot/grub
insmod normal
normal


This brings up my grub boot menu and allows me to load Linux Mint 18.3 normally but it is not permanent, a reboot brings up the grub rescue prompt.

I read in another post that the solution is to go into a terminal window and issue the commands;
sudo update-grub
then
sudo grub-install /dev/sdx
where sdx is my linux partition

This does not work, and gives an error message (I can't remember what it was right now.)

I found another post from the same person saying that the solution to that problem was to use the chmod command then issue the update-grub and grub-install commands.

I tried to do this but can't figure out how (No further explanation was given in the post I read.) Everything I tried resulted in an error message.

Can anyone tell me how to make the grub repair permanent?

Hi Laurent85, I did not need a live usb, I can boot Linux 18.03 using the grub rescue commands I listed.

Here is the output I gotfrom the commands you suggested:

sudo parted --list --script

This is where Grub should go. You have a GPT partition table and are using UEFI for booting. See the flags at the end of the line? That means the EFI partition is the boot partition and Grub should be located there.

Here is mine from my iMac.

Code: Select all

Number  Start   End     Size    File system     Name                  Flags
 1      20.5kB  210MB   210MB   fat32           EFI System Partition  boot, esp
So I think your command should be:

Code: Select all

sudo grub-install /dev/sda2

Thanks for the suggestion CaptainKirksChair, but I had already tried this and it does not work ... returns the error message shown below.

~ $ sudo grub-install /dev/sda2
Installing for i386-pc platform.
grub-install.real: warning: File system `fat' doesn't support embedding.
grub-install.real: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
grub-install.real: error: will not proceed with blocklists.


When I researched that error message I found a post saying that the chroot command must be used before update-grub and grub-install but as I said in my original post I can't figure out how to do this. All my attempts result in error messages and failure.

Did you try to reinstall grub ? The grub version you are running is not grub uefi but grub for bios (Legacy).

Re: grub rescue problem

Post by handyman4848 »

Laurent85, the grub version I am running was installed when I installed Linux Mint 18.3 following a hard drive re-format and Windows 10 install.

Everything was fine for some time, then I added Ubuntu 18.04 to try it out, which of course did a new grub install. I then decided to remove Ubuntu 18.04 and deleted the Ubuntu 18.04 partitions. That is when my grub problems started.

Grub works fine after entering the previously mentioned commands at the grub rescue prompt, I just can't make it permanent.

Install efi-grub

Code: Select all

sudo mount /dev/sda2 /boot
sudo mkdir -p /boot/efi/EFI/ubuntu
sudo apt-get update
sudo apt-get install --reinstall grub-efi grub-efi-amd64
sudo update-grub
If EFI-partition is not in the /etc/fstab file, add it.

So Mint was mistakenly installed in Legacy mode, reinstalling grub fails with your uefi setup.

Thanks administrollaattori. Not sure what you mean by "If EFI-partition is not in the /etc/fstab file, add it."

Would that be my sda2 partition?

This is my /etc/fstab file.
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Would that be my sda2 partition?
Add the next line to the /etc/fstab file

Code: Select all

UUID=06AE-45EF  /boot/efi  vfat  defaults  0  2

Code: Select all

sudo nano /etc/fstab

Re: grub rescue problem

Post by handyman4848 »

Well, I tried what you suggested administrollaattori, but no joy. I used cut and paste to make certain there were no typos or other errors but I still get a grub recue prompt when I try to boot up the system.

The only thing that works is:
grub rescue> set root=(hd0,gpt6)
grub rescue> set prefix=(hd0,gpt6)/boot/grub
grub rescue> insmod normal
grub rescue> normal


This brings up my normal grub boot menu from which I boot my system into Linux Mint 18.3 Cinamon as always.

What I cannot do is find a way to make this happen automatically as it should.

I did read a post on the ubuntu forums saying that it could be made permanent with the commands:
sudo update-grub
sudo grub-install /dev/sdx


This was followed by a post saying that it did not work then a second post from the same person saying problem was solved by using the commands;
chroot, update-grub, grub-install /dev/sdx
with no further explanation.

I tried to do this but was unsuccessful, and reading man chroot did nothing to clarify the issue for me.

Since grub rescue commands will bring up my normal grub boot menu there must be a way to make this happen automatically when I boot my computer. So far all I seem to have accomplished is to clutter up my /boot directory with a bunch of un-necessary directories and files.

Is your computer in Legacy BIOS or UEFI mode?

Code: Select all

[ -d /sys/firmware/efi ] && echo "EFI mode" || echo "Legacy Bios mode"

It looks like I am in legacy bios mode.

Re: grub rescue problem

Post by handyman4848 »

administrollaattori, I don't know if this is relevant, but to boot into Windows I need to press F12 for the Boot Menu and select "Windows Boot Loader" or "EFI xyz" where xyz is the UUID of sda. To boot Linux I would press F12 for the Boot Menu and select the UUID of sda, not the EFI version. Once selected the choice is persistent until changed.

Do not use Legacy Bios mode. Use UEFI mode with both of systems. :wink:

PS. Set "ubuntu" as the first bootable system over "Microsoft boot loader" in the BIOS-settings.

OK. Install rEFInd (Debian package).

Re: grub rescue problem

Well administrollaattori, that did not work either. The install seemed to complete normally but a reboot gives the same results as before and selcting an EFI boot from the bios boot menu just launches Windows as before.
