Unable to boot into freshly installed system due to vfs unable to mount root fs on unknown block(0 0)

Issues & Assistance
1

Hi I tried to install a Garuda Linux and completely wiped all old partitions. During installation I did not see any errors but when I boot I get. vfs unable to mount root fs on unknown block(0 0)(when freshly installed there’s a longer message but I tried using chroot and updating system). I already tried reinstalling multiple times. I also tried to chroot(using button in live usb) and when I do that I see this output:

grub-probe: error: cannot find a GRUB drive for /dev/sdc2.  Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sdc2.  Check your device.map.

I tried to use garuda-update once and it just changed the way blue screen looks but error seems to be the same. Also I am not sure if this is related to this issue or not but I was only able to boot into live usb from Ventoy only by using grub2 mode. I would see black screen or black screen with single short white line(depending on edition) otherwise

garuda-inxi output from live usb:

Well, if it’s a GRUB problem, you could try a sudo grub-install from the local installation to re-install it. It should automatically create boot entries for any OS it finds.

For garuda, there is garuda-update remote fullfix to “reset pacman.conf, refresh keyrings, and reinstall all packages in your OS.”. See garuda-update --help for more options.

Do make sure you chroot into the correct environment or this could just make things worse.

When in your local installation, check /boot/efi exists. It has to be a separate FAT32 partition with at least 300MB.

If this doesn’t help, posting your full lsblk might be helpful.

Thanks for your reply
For purity of experiment I reinstalled Garuda once again. And this time with Windows alongside. Then executed both grub install and garuda-update remote fullfix from chroot. It didn’t help. Also now when I chroot before grub-probe errors here are

/usr/lib/os-probes/50mounted-tests: line 186:  7054 Segmentation fault      (core dumped) grub-mount "$partition" "$tmpmnt" 2> /dev/null

These messages already appeared but I managed to fix them somehow(I don’t remember how).
Here’s output of lsblk

Mmh… Comparing this to my setup, using different physical disks, it strikes me that Windows uses 4 partitions and Linux uses 2 (at least), but you only have 5. Also, sda1 which is mounted to /boot/efi only has 100MB. That’s the Windows size, wheras Calamares uses 300MB as a default.

Remember me saying earlier that Redmond eliminates the competition if installed after Linux? (That was a different thread.)

Looks like Windows killed the Linux bootloader partition.

This is what is looks like on my system. nvme0 is Windows and nvme1 is Garuda.

It would probably be easier to re-install everything over trying to fix this mess. But make sure to install Windows first, then Linux. In Calamares, make sure to do manual paritioning to preserve all Windows partitions as is.

Why? M$ is installed.

Instead install everything again:
You can chroot and repair grub, often explained in this forum.

If so, it is sufficient to install Garuda next to M$ on the corresponding partition. There is no need to partition anything yourself.

And just use lsblk -f, looks like

lsblk -f | grep 'sd|NAME|nvme'

After that you must use

sudo update-grub

is not needed

I actually recommended that first, but it didn’t work. Possibly, because the sda1 partition mounted to /boot/efi has been overwritten and shrinked by Windows.

But yes, if Windows works, there is no need to reinstall that. Just clean up the Linux partitions and go from there.

I use 4 OS on this notebook, my efi use 260 MB

the OS’s need just 40.29 MB, so for two OS 100 MB are enough I think, but I can fail :slight_smile:

Reinstalling and partitioning manually did not help at all. Same issue

Is using button in welcome menu to chroot appropriate for this tutorial?

Yes, if you set the chroot with the GUI tool you can skip down to this part:

That looks good, assuming sdc is your thumb drive or something else.

13

If that’s the case updating grub didn’t help. Same issue

14

Not direct your problem but your MB like a bios update
After this, check the relevant entries that you can boot your garuda linux.

15

Which 4 OS do you have on the Notebook SGS?
Just interested that’s all.

16

A question is for me, what is sdc ?

Disconnect pls..before you work on your system.
Some error messages come from this. If this relevant, not shure, i mean not.

17

@ Hamster … these or ?

That is, if your initramfs is not sync to kernel boot (grub)
Use the live iso → chroot and rebuild your initramfs
dracut-rebuild then run update-grub
result = ?

19

What is the blue screen? Is there a message?

If it looks like this, check that secure boot is disabled:

Thanks everyone for trying to help to solve this problem but I decided to go with pure Arch instead(primarily because of performance). Even there I had some issues with setting up grub but after I mounted Windows boot partition properly everything seems to work fine. Sorry for not finishing this. (should i mark this as solution?)
