[Solved] Can't boot - invalid cluster 0

Hi there,

Here's the picture. I've got a dualboot system: sda is Archlinux, sdb is Windows 10. Everything worked fine. Then, Windows installed one of those automatic updates and activated Fast Boot without my knowledge. I also have Paragon ExtFS installed and accessed my Linux partitions to open a PDF file (I also accessed boot partition, but made no changes in it). Now, when I try to boot Arch, I get the following message:

error: invalid cluster 0.

Then:

Kernel-panic - not syncing: VFS : Unable to mount root fs on unknown-block(0,0)

I booted Arch using an install image (USB-key). Change-rooted, updated packages and reinstalled Grub. Still the same messages when trying to boot.
Any ideas?
Thanks.

If you can chroot and update packages the filesystem seems to be fine, at least from a glance.

What is your fstab configured to? if you use /dev/sda and /dev/sdb you really don't want to do that: https://wiki.archlinux.org/index.php/Pe … ice_naming

Here's my fstab:

Re: [Solved] Can't boot - invalid cluster 0

Ok. I've got a doubt. When change-rooting, I just do

mount /dev/sda2 /mnt
arch-chroot /mnt

Since root and boot are in different partitions (sda2=root and sda1=boot), should I mount sda1 too? How? Or I just do

mount /dev/sda /mnt

and I get everything mounted?

Re: [Solved] Can't boot - invalid cluster 0

Tried the following thing:

mount /dev/sda2 /mnt
arch-chroot /mnt
mount /dev/sda1 /boot

Then, reinstalled grub. Still nothing. I have no idea of what's going on. Having searched the forum ant the net, I couldn't get any hint.
I don't wanna reinstall Arch, cause it's completely configured for my needs and I don't wanna spend again the huge amount of time I put into it.
Any help is appreciated.
Thanks.

Well unless you made a mistake during copying, currently all your entries are commented out. put a newline before the UUID identifiers.

I think it was a copy problem. Here's the actual fstab:

Re: [Solved] Can't boot - invalid cluster 0

That looks alright, can you fsck your root and boot partitions? You might want to explicitly reinstall the kernel package when in the chroot (ensuring that /boot is properly mounted) I've seen similar with corrupted files on the ESP, did you check that you still have enough free space on the ESP partition to contain the kernel image?

Re: [Solved] Can't boot - invalid cluster 0

ESP has 490mb of free space.
I'm mounting the boot partition this way, after chrooting:

mount /dev/sda2 /mnt
arch-chroot /mnt
mount /dev/sda1 /boot

Is this the right way?

Re: [Solved] Can't boot - invalid cluster 0

Yeah that should be fine, fsck it (needs dosfstools) before mounting, then mount (to be extra sure, manually remove your initramfs and kernel images ) and reinstall the kernel, I faintly remember having this one time, where simply the file name table of the FAT partition was corrupted and the kernel couldn't be located despite the file itself having been written properly.

Re: [Solved] Can't boot - invalid cluster 0

Sorry for my ignorance, but how can I manually remove your initramfs and kernel images? Using pacman -R?

Re: [Solved] Can't boot - invalid cluster 0

no just delete them with rm, especially the initramfs is only generated afterwards by mkinitcpio and not tracked by pacman.

But if it's similar to the issue I had, as far as I remember a fsck was enough to fix it.

Re: [Solved] Can't boot - invalid cluster 0

And where are initramfs and kernel located?

Re: [Solved] Can't boot - invalid cluster 0

Well, there was no initramfs. Did a update, installing the new kernel and it worked fine.Thanks for your great help.
