Fstab file looks like this:

[drrummer]

The following is how my fstab file looks. I was thinking of changing the mountpoint of the Windows partition. However, the UUIDs don't exactly match the UUIDs I see in Gparted. Also, why are there reptitions, is this normal ? Thank you.

...is this normal ?

Nope, but is has me intrigued.

G'day @drrummer

1. Could you please give us the output of

blkid

and

cat /etc/*release

2. Are you still using the Chromebook?

yep that is one convoluted fstab

Hi Thank you for your reply.

The output of blkid is:

Thanks for that.

I was thinking of changing the mountpoint of the Windows partition.

1. May I ask for what purpose, or what is it you are looking to do?

2. The following lines could be deleted, just to clean up, if you wish, they are only commented, and make no difference to your environment - might be a legacy (leftover) of a previous EFI partition or flash drive

#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1

#UUID=D282-B9DE /boot/efi vfat defaults 0 1
#UUID=D282-B9DE /boot/efi vfat defaults 0 1

3.

/dev/sdb1 /mnt/sdb1 none nosuid,nodev,nofail,x-gvfs-show,x-gvfs-icon=Sam,noauto,x-gvfs-name=Samsug%20HDD 0 0

looks like you have already performed a mount of some type on another drive, is that so?

4, You could delete one of the lines saying

#UUID=D098-3AEB /boot/efi vfat defaults 0 1

as they are just duplicates.

5. From the fstab output

# /boot/efi was on /dev/nvme0n1p1 during installation
#UUID=D282-B9DE /boot/efi vfat umask=0077 0 1

appears to indicate that that was the original EFI system partition - has something been moved from Computer A to Computer B?

6. You have said

However, the UUIDs don't exactly match the UUIDs I see in Gparted.

... so you will have to give us more detail, if you wish us to compare and provide ideas.

Cheers

Oh-just figured out how to break up the quote.. No, not using that Chromebook now. I just keep it for times when I break this machinne.

1. May I ask for what purpose, or what is it you are looking to do?

Because...at one point, in an effort to resize partitions, I wholesale c+ved the entire contents of the Windows partition to another drive. Then when I put the contents back to the partition, Windows doesn't appear as an option in the Grub menu.
Furthermore, the drive I used was from an old Windows machine. So now I may have content from that OS there too.

2. The following lines could be deleted, just to clean up, if you wish, they are only commented, and make no difference to your environment - might be a legacy (leftover) of a previous EFI partition or flash drive

Okay. Will do, thank you.

3. looks like you have already performed a mount of some type on another drive, is that so?

Yes. I have some external drives which I have connected from time to time. I might reconnect those and figure out which UUIDs match.

4, You could delete one of the lines saying as they are just duplicates.

I presume you mean 'all but one of the lines' ?

5. From the fstab output


appears to indicate that that was the original EFI system partition - has something been moved from Computer A to Computer B?

The original setup was just a Windows OS. But I installed Linux Mint in dual-boot format.
Other than that, I moved stuff from dev/nvme0n1p3 to an external drive, if I remember correctly, as mentioned above.

6. You have said



... so you will have to give us more detail, if you wish us to compare and provide ideas.

The UUIDs are:

• D098-3AEB
• 7B6C6F906B5B43A5
• 65AFDA5A363495C6
• 510adab1-194c-4502-80e3-a0a468ca2366

Bump.

 

[KGIII]

There aren't that many posts or helpers, so there's generally no need to bump stuff. Folks will have seen your post and those that know will try helping. If the thread goes dead, it often means nobody knows how to help you.

Fair enough. I just thought a bump might help. Not to worry.

 

[Alexzee]

Agreed-

Don't give up hope. Someone may come along with the answers you need. I read the thread and I am not sure how to help you.

It's been my experience (coming to this Forum over the years) if you try to put back an os and the partition that it's on onto the original device that you took it off of : it won't boot because Grub doesn't know about it.

Have you tried updating Grub?

 

[Alexzee]

Unmounted /boot, deleted from /etc/fstab, from where exactly GRUB take its settings?

I unmounted and removed the entry line in /etc/fstab regarding my /boot partition. The hero of all Unix questions Gilles here actually mentions this: "No, /boot isn't needed during normal system

Even if you get grub to try and boot from the windows partition now, i doubt that it will successfully do that. Windows does all kinds of obscure stuff with the drive it's insatlled on. A repair might work, but then Windows will mess with the entries on the efi partition and you won't be able to boot linux until you reverted those changes. You'd need to do that without the linux drives present, then when windows is working again, put the linux drive(s) back and change the boot drive back to the one where grub is located.
It might be better to just reinstall Windows on a clean drive (also without the other drive(s) present). You'll end up with a mess otherwise..

Yes, leave the one at the bottom that has no comment.

You will need to give us the GParted output or discrepancies so that we can compare.

BTW I am unbumpable, I get back when I can.

Yes, I have. To no avail. I try to find alternative solutions, but I always fear bricking my machine.

Do you have the Windows installation disks?
