Fixed it till it broke - GrubF*ckup?

I remembered that I had a dusty partition with Manjaro on it so I deleted the partition
Even managed to delete the right one LOL
Then I did grub-update

But, now my AL doesnt boot - I get a ‘Welcome to GRUB!’ flashing up then it goes into BIOS
If I then put Windows 10 at the top of boot sequence it works
None of my live Linux USB’s boot - AL one gets stuck at mirrors and stuff, my ArchBang one goes straight to BIOS. The MX tools one works but I havent found any respite in the grub rescue options

The thing is - I did some work arounds with my grub due to the Manjaro + AL (or anything else?) problems before:

NB I currently only have AL and Win 10 on the lappy

Can anyone offer the best way forward for me please?

Please! before I cry.

I’m thinking that I might have to undo my previous grub edits?

But I cant get any bloody linux usb’s to work

I am currently in Win 10

At least this didnt happen when I have loads of work to do, 3 cubic meters of earth being delivered that I have to wheelbarrow up the drive as the truck is too big to get in, its finally going to rain today after a long hot summer, and my parents are arriving to visit for a week or so and I have to go to the airport at lunchtime


I just remembered that in Win10 I installed DiskGenius and I can view my AL Ext4 linux files from there, but dont think I can edit them

There appears to be nothing at all in my AL /boot - at least from windows according to DiskGenius where I can see and view other files

I have got another lappy with AL on it that I can use to redo my USB live AL which is a bit old now

To make it easier - my post from other thread:

I have a workaround :

Make a custom grub entry in Archlabs’ grub to chainload the Manjaro grub
(Inspired by this post on the Mint forums)

1/ In Archlabs:

sudo nano /etc/grub.d/40_custom

insert the last two lines:

exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Manjaro GRUB chainloader" {
 chainloader /efi/Manjaro/grubx64.efi

2/ update grub:

sudo grub-mkconfig -o /boot/grub/grub.cfg

(or install and simply use update-grub wrapper thingy)

3/ Set laptop to boot 1st to Archlabs via firmware UEFI settings

4/ Use the Archlabs GRUB menu for Archlabs, EOS and Windows
[EDIT: in fact to get EOS to boot from the Archlabs GRUB menu I had to edit /boot/grub/grub.cfg to add the missing /boot/initramfs-linux-lts.img to the initrd line under the EndeavourOS Linux menuentry - I have no idea why (I did try to update-grub in EOS and then in Archlabs, but it didnt add that bit) and this edit was undone on grub-update, so is a very flakey solution :slight_smile: )]

5/ Or use the ‘Mangaro GRUB chainloader’ entry to go to the Manjaro GRUB menu if I want to boot to Manjaro,

But, I dont think I will be doing 5/ very often as I MUCH prefer Archlabs [Openbox] & EOS [i3] :smile:
[EDIT #4: I edited the Manjaro GRUB to set Default to 0 (1st, entry, Manjaro) and set the delay to 0 sexonds so that I dont even see the Manjaro GRUB menu before it boots into Manjaro]

Now to find out how to remove grub menu entries that wont work to tidy up …
[EDIT#3: I just cut the relevant Manjaro menuentries out of /boot/grub/grub.cfg to carry on my flakey solution :)]

EDIT #2: NB I installed Archlabs and EOS on another laptop with no Manjaro and there were no such problems

Walk away from it. Go shovel dirt. Eat a meal with the parents. Have a good night sleep. Start fresh in the morning.


it is morning and I am fresh LOL
I went to start the garden, buy some seed and fertilizer
Garden Centre only opens on Tuesday.

So, I got my AL usb to work / reflashed new iso - had to be the LTS one and only worked in my USB 2 port for some reason. But then using that as a live iso needs doing all that Pacman and mirrors malarky so I downloaded and flashed to USB stick the Endeavour OS live iso on the other lappy and now am in linux on my main lappy

I started by deleting the following from /etc/grub.d/40_custom on my now unaccessible AL installation

menuentry "Manjaro GRUB chainloader" {
 chainloader /efi/Manjaro/grubx64.efi

Then I went to see if my modification to /boot/grub/grub.cfg was still there .

But there is indeed nothing at all in /boot on my main installation

I do not understand LOL

Next step
I installed another instance of Archlabs on a new partition where the Manjaro one was
That worked, and now I have a grub menu with the two Archlabs and the windows one

but the new Archlabs doesnt boot up
Failed to mount /boot

Then into emergency mode

If I try to boot into my old archlabs it says that
/boot/initramfs-linux-blah-blah not found

When I installed the new archlabs I chose to use grub (I thought it migh ‘sort it out’) and I didnt format the boot partition (sorry - I forget what that is called, the first partition on the disk)
Should I have formatted this?
Or would that mess up my Windows installation too?


We need more info. Post lsblk. Describe each drive and partition.


Post output of:

sudo fdisk -l

as well.

You need to determine the partition layout and which are being used by Windows.

Are there two hard drives in the laptop?

Might be easier for you to boot Windows and get into the control panel and view the disk(s) partitions.


Thanks @eight_bit_al @PackRat

First thing you need to do is back up your work files on /dev/sda9 and /dev/sdb1

Is that plug and play where you can just remove it? If you can do that without losing the data, you can get it out of harms way and avoid a catastrophic accident.



I back up all my personal (sda9) and work (sdb1) files onto an external hard drive every day
Did that last night

I also do a weekly backup on another external hard drive every Friday

My personal files are on sda9

My work files are on sdb1

I have to take the laptop apart to get the sdb disk out

You’ll want to mount that partition from the Endeavour OS live system and copy the configuration and dotfiles you want to save.


There are your Windows 10 partitions don’t format those.
Do you have a Windows 10 install media in case this goes bad?


Done, although I am not sure if that is all of them:

[liveuser@eos-2022.09.10 ~]$ ls -a /run/media/liveuser/USB_STICK/Archlabs/
.           ArchLabs.conkyrc  .gtkrc-2.0        .lyxauth     .xprofile    .zshrc
..          ArchLabs.tint2rc  .jgmenu-lockfile  .Xauthority  .Xresources
.aliasesBU  .gtk-bookmarks    .kickshawrc       .xinitrc     .zprofile

Yup, but really hoping not to have to do that as I have lots of software etc setup on that Win installation LOL

You’ll want the files in ~/.config
Lie your i3 and openbox config files.


@PackRat - thanks for your help!

Copied them all across to USB stick -it did say 10 hours to complete but now its finished
I had to skip symbolic links in case this is important

Is this all an in case thing? Am I going to try to keep the installation but if it goes tits up then I have the backups - or is a complete reinstall needed?

Thanks again

It’s just backup in case things go bad.


I’m not sure if you’ll need a complete reinstall; but you could end up with an odd partition scheme.

Were you set up with Win10 and Linux sharing the EFI partition?

Edit - reinstall of Linux, your Win10 should be ok.


I thought so. I presumed that this was the way it worked
But now you have asked, I am not sure.
How would I be able to tell?
It all got complicated by that pesky Manjaro installation

I think that’s what you were doing.

I need to research this some more. I don’t dual boot from a single drive. I have one drive Windows, one Linux.

I wasnt doing this, i.e. not everything on the same disk.
During installation of Archlabs I selected sda1 as the boot partition, so I guess Win, Manjaro and AL were all using the same EFI partition?
