For some reason I can't label it. I can only flag it. I can only label my NTFS partition in sdb
Here's the command inputs:

Code: Select all

mint mint # mount/dev/sdb1 /media/SDB1
bash: mount/dev/sdb1: No such file or directory
mint mint # sudo gparted
======================
libparted : 2.3
======================
ls /media
I think I'm not able to fix it myself ;'(

Oh, nvm. I just had to unmount the drive :p

Hi!
Please run GP, maybe you must "unmount" sdb1, afterwards it must be possible to edit the label: 48f7fe4d-eb94-4711-a9dc-ee54d409adf4 -> rootMint.
After having rebooted, open a Terminal, and the best (first action in Terminal, every time on live medium) would be: first type "sudo su" to have root rights for all commands:

Code: Select all

mint@mint ~ $ sudo su

Code: Select all

mint mint # blkid
- "#" shows: root rights -
You should see:

Code: Select all

/dev/loop0: TYPE="squashfs" 
... 
/dev/sdb1: LABEL="rootMint" UUID="48f7fe4d-eb94-4711-a9dc-ee54d409adf4" TYPE="ext4" 
...
mint mint #
[/color]
I suggest: please do that, staying on live medium - as root in Terminal - and post from there, then I will give you the next command(s).
Step by step we should locate the problem.

I see you're online atm, could u pls at me in your msn list? I'll go online by ebuddy. Is that ok?

Here's the information u asked for:

Code: Select all

/dev/loop0: TYPE="squashfs" 
/dev/sdb1: LABEL="rootMint" UUID="48f7fe4d-eb94-4711-a9dc-ee54d409adf4" TYPE="ext4" 
/dev/sdb3: UUID="09B1A9E70C88019E" TYPE="ntfs" 
/dev/sda1: LABEL="Door systeem gereserveerd" UUID="62FA8E2FFA8DFF91" TYPE="ntfs" 
/dev/sda2: UUID="44C87660C8764FE2" TYPE="ntfs" 
/dev/sda5: UUID="76c405b5-5045-4883-9e0f-429670371159" TYPE="swap"
Door systeem gereserveerd = Reserved by (file)system

I'm happy I can do this the Linux-way cuz I'm getting some knowledge bout the terminal :D

Hi!
I have a hardware problem and my vacation starts at Monday, so afterwards I will be offline for several weeks.
We should try to solve the problem today - I will stay here most time of the day.
Please perform all suggested steps and report - from live medium.
seeley

Edit:
I did not see your complete post. First step done. As root (sudo su) >
Now - error message "... can't create, exists..." can be ignored:

Code: Select all

mkdir /media/rootMint
and then:

Code: Select all

mount /dev/sdb1 /media/rootMint

Code: Select all

mint mint #     mkdir /media/rootMint
mint mint #     mount /dev/sdb1 /media/rootMintµ
mount: mount point /media/rootMintµ does not exist
mint mint #     mount /dev/sdb1 /media/rootMint
Done, no complications (the µ is just an enter fail ;p)

Edit:

I tried to go on:

Code: Select all

mint mint #     sudo grub-setup -d /media/rootMint/boot/grub /dev/sdb
Segmentation fault
mint mint #     sudo grub-setup -d /media/rootMint/boot/grub /dev/sda

Hi!
Okay. Next steps: (you are root?!)

Code: Select all

cd /media

Code: Select all

ls -l
- lowercase "L" like list

You should see > rootMint

Code: Select all

cd rootMint
You should see > ...,boot,...

Code: Select all

cat boot/grub/grub.cfg
copy and save and post.

Hi!
Everything - as fare as I see - seems to be okay.
You are on Terminal as root, see if sdb1 is mounted:

Code: Select all

mount
You should see maybe 6 - 12 lines, one containing "...sdb1 on rootMint..."
Next, last and important command on live medium:

Code: Select all

sudo grub-setup -d /media/rootMint/boot/grub /dev/sda
Afterwards reboot - without live medium - and:
no error -> boot to Mint Desktop and there Terminal:

Code: Select all

sudo update-grub
reboot again, boot to mint from hd and report.
If any error message, please report.

Hey, I just rebooted my laptop. (still got the rescue message like you expected ;p)

Here's the new output:

Hi!
To see if your boot.img exists: Open Terminal: (if open, close and reopen)

Code: Select all

sudo su

Code: Select all

ls -l
You see "rootMint" >

Code: Select all

mount /dev/sdb1 /media/rootMint
"...mounted or busy..." can be ignored

Code: Select all

cd rootMint

Code: Select all

cd boot

Code: Select all

cd grub

Code: Select all

ls -l
You should see many lines, one containing "...-rw-....root 512... boot.img"
If not, you have to make a fresh installation,
if yes, the file can be corrupted (we can not see it - only suppose).
Plaese report; stay on live medium.

Hi!
Maybe the problem is that you have 2 hard disks. At the moment I don't have another idea.
Sorry. But I will search a while.
The file is: boot/grub/device.map.

OK, thx for your help so far.
I think that the source of the problem is that I originally installed LM9 on my sda drive. I just formatted that partition and installed LM10 on a new partition located in my sdb drive. I could just restore the original windows MBR files, i think, using PartitionMagic (cuz it uses Super Grub Disk or something like that). If I'd do that I think I would be able to install grub on my sdb drive (by reinstalling LM10 maybe or by apt-get). The original file is restored and it will be edited by the new grub 2 with, I think, removes the problem. Could this be correct to assume?
