[SOLVED] Partition do not mounted

I've a laptop with a 1Tb primary hard disk and a 120 Gb secondary hard disk where I used to save personal files during the migration to linux.

I had installed archlinux and everything worked correctly but yesterday I've tried to install a dualboot of arch and fedora (I was going to test even that distro).

However, after installation fedora didn't appear in the initial grub, so I've decide to reinstall the grub with the command

sudo grub-install /dev/sda

Here the problems began. I've accidentally installed grub on my secondary hard-disk partition and now I can’t access anymore to that disk.

This is the error message:

Error mounting /dev/sda2 at /run/media/gim/Disco locale: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error 

Someone can help me?? Please I had important documents on that partition. I’m desperate to find a solution

I've list the partitions with fdisk -l and this are the information about that partition:

Disk /dev/sda: 119,24 GiB, 128035676160 bytes, 250069680 sectors

Re: [SOLVED] Partition do not mounted

Why do you label the 120 GB SSD your "secondary" disk even when linux enumerates it as the first disk (sda)?
Why do you try to install grub to your "secondary" disk - does that make sense to you?
What is your default grub target? Run

grub-install --help

and look for the default under the "--target" option.
Did you do

sudo grub-install /dev/sda2

too or why do you think you accidentally installed grub in this partition?
What is the partition layout on your 1TB drive?
What is your boot mode (BIOS/CSM or EFI)?

Hi, thanks for the answer.

The default target is "x86_64-efi"

Anyway, idk why my sda is the secondary disk and sdb is the primary, but was a fault install grub on sda and now I don't know how to solve this situation and restore my file...

I've done both

sudo grub-install /dev/sda

and

sudo grub-install /dev/sda2

The 1Tb drive is the SDB partition and is the one where there's installed linux now and before windows (yes i've just switched from Windows so sorry if I'll commit some errors)

I think my laptop's bootmode is bios (when i reboot it says "press F12 for Bios")

Re: [SOLVED] Partition do not mounted

Please post the output of

sudo fdisk -l /dev/sdb
cat /sys/firmware/efi/fw_platform_size

If the output of the second command is empty, please mention it.

Just to prevent misunderstandings:

Whole disks:
/dev/sda
/dev/sdb
...

Partitions:
/dev/sda1
/dev/sda2
/dev/sda3
...
/dev/sdb1

Re: [SOLVED] Partition do not mounted

Over-writing the MBR should not have affected the data partition. Not sure if GRUB will use the i386-pc target automatically if booted in non-UEFI mode though.

@OP:

Did the grub-install command return any error messages?

In which context do you see the /dev/sda2 error message?

A full journal from that boot would probably be useful for us.

No, the grub install do not report any error.

The error message appear when I try to open sda2 with File manager.

How can I produce the journal? Sorry for the stupid question

Re: [SOLVED] Partition do not mounted

Run this command:

journalctl -b 0 | curl -F 'file=@-' 0x0.st

Then post the returned URL here.

You are booted in UEFI mode so the grub-install command would have just installed the modules to /boot/grub/ and core.img to /boot/efi/EFI/arch/grubx64.efi.

Please share the output of

lsblk -f

And `fdisk -l /dev/sdb`, as requested by -thc.

Re: [SOLVED] Partition do not mounted

You have a system running in 64-bit EFI mode.

The "grub-install" commands you entered should not work and should do no harm.

@Head_on_a_Stick: Is "/boot/efi" the default for grub-install?

I think so, yes. Unless it's changed recently ofc.

Re: [SOLVED] Partition do not mounted

I can’t really understand why it doesn’t make me access this disk anymore...
There's any chance to recovery it?

Re: [SOLVED] Partition do not mounted

Well that Fedora system isn't right, the root partition has an ESP GUID and it has it's own ESP as well. Not really relevant here though.

Re: [SOLVED] Partition do not mounted

I'm sorry - I can't help you - too much chaos for me.

If only the NTFS dirty flag is set a simple

ntfsfix /dev/sda2

should probably help.

Re: [SOLVED] Partition do not mounted

Anyway, idk why my sda is the secondary disk and sdb is the primary

The enumeration isn't deterministic why you're supposed to use UUIDs

For the bigger picture, why is there an NTFS partition, but no windows?
Do you have a 3rd disk w/ windows on it?

Fixing ntfs w/ chkdsk (windows tool) is preferable over ntfsfix, esp. if you've important data on it.
It'd probably even be a good idea to create a backup image of the damaged disk to have a homebase if you screw things up even more.

Until a couple of weeks ago I had windows, then I've installed Arch Linux. When I've done the migration I've copy all important files in sda and installed linux on sdb. Maybe for this reason it is NTFS.

Anyway, how can I do the command chkdks? I've wrote it in the terminal but it says that the command wasn't found.

I've done even the command ntfsfix but it hasn't worked for me.

Thanks in advance.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
Did you get some error?
In doubt see https://wiki.archlinux.org/title/NTFS#U … rked_dirty

nb. that the FS is marked dirty for a reason, and just clearing the flag might cause data loss.
Try to mount it read-only w/ https://wiki.archlinux.org/title/NTFS-3G and ensure to access/secure all relevant data first.

If you've access to a windows installation, use that to chkdsk it.
Then migrate away from NTFS, it's no a first-class FS on linux (reverse engineered and feature incomplete, regardless of the driver) and there's no point or reason to use it if you don't have frequent access to windows.

Re: [SOLVED] Partition do not mounted

When I do ntfsfix command the output is:

Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... OK
NTFS volume version is 3.1.
NTFS partition /dev/sda2 was processed successfully.

Why it says that the mounting volume is OK but it doesn't opening?

Re: [SOLVED] Partition do not mounted

ntfsfix is part of ntfs-3g which is way more lenient reg. the dirty bit.
You're gonna be able to mount the partition using ntfs-3g.

Finnally I solve with the command:

Re: [SOLVED] Partition do not mounted

You can remove the dirty bit w/ "ntfsfix --clear-dirty", see the previous link, but you should *really* seek to chkdsk the partition and/or transfer your data to a FS you can actually properly maintain.
