How to change the size of partitions? (resolved)

[Tramlink]

All the most important documents are held in dropbox and the system is backed up to a Drive on the LAN.

What I have noticed is that I could not reduce the size of "resize the extended partition to be just big enough to contain sdb5 (swap)"  I had to extend the extended partition to fill the drive and then........ resize sdb7 to fill the rest of the drive (the extended partition).

At present this will take another hour and 5 mins.

Sorry .. I thought sda7 was outside the extended partition .. that should be fine.

OK, whilst still booted to the LivecD .. open a terminal  and run:
sudo mount /dev/sdb6 /mnt
then
sudo grub-install --boot-directory=/mnt/boot /dev/sda
now REBOOT to the hard drive (ie. without the LiveCD)

It should boot into Mint 13 .. then in Mint 13, open a terminal and run:

Code: [Select]

sudo update-grub

When that's done .. reboot to see that you're offered both Windows and Mint.

Mint and windows working just fine.

By-the-way 

sudo update-grub

dose not exist on my system.

But this did not cause any problems.

Thanks for the assistance.

[Mark Greaves (PCNetSpec)]

Are you sure .. it should

So what's the output from:

Code: [Select]

sudo update-grub

?

userone@office2 ~ $ sudo update-grub

[Mark Greaves (PCNetSpec)]

Can you post the output from:

Code: [Select]

dpkg -l | grep grub

[Tramlink]

userone@office2 ~ $ dpkg -l | grep grub
rc  grub-common                                                 1.99-21ubuntu3.1                        GRand Unified Bootloader (common files)
rc  grub-pc                                                     1.99-21ubuntu3.1                        GRand Unified Bootloader, version 2 (PC/BIOS version)

sudo: update-grub: command not found

The command for "update-grub" (as used by Ubuntu) is just an alias.
The real grub2 command would be

Code: [Select]

sudo grub-mkconfig -o /boot/grub/grub.cfg

If you'd like functionality like that, just add this to your ~/.bashrc file:

Code: [Select]

alias update-grub='grub-mkconfig -o /boot/grub/grub.cfg'

Log out and back in and run as normal:

Code: [Select]

sudo update-grub

[Mark Greaves (PCNetSpec)]

Is it just me ?

These seem to be missing
grub2-common
and
grub-pc-bin

and possibly:-
grub-gfxpayload-lists

And as far as I'm aware, there's no alias in *my* ~/.bashcr

[SeZo]

And as far as I'm aware, there's no alias in *my* ~/.bashcr

That would be OK on Ubuntu (and derivatives) as it is a built in command.
However on other distros you get grub 'neat' but you could make that command available as an alias

These seem to be missing
grub2-common
and
grub-pc-bin

You are right:

rc  grub-common                                                 1.99-21ubuntu3.1                        GRand Unified Bootloader (common files)
rc  grub-pc                                                     1.99-21ubuntu3.1                        GRand Unified Bootloader, version 2 (PC/BIOS version)

That 'rc' would indicate that the package was removed, but that the configuration files are still there.

[Mark Greaves (PCNetSpec)]

Yeh, I missed those rc(s) .. so there are at least 4 missing packages.

Here's mine (Peppermint 3 - Ubuntu 12.04)

mark@AA1-Blue ~ $ dpkg -l | grep grub
ii  grub-common                               1.99-21ubuntu3.7                                  GRand Unified Bootloader (common files)
ii  grub-gfxpayload-lists                     0.6                                               GRUB gfxpayload blacklist
ii  grub-pc                                   1.99-21ubuntu3.7                                  GRand Unified Bootloader, version 2 (PC/BIOS version)
ii  grub-pc-bin                               1.99-21ubuntu3.7                                  GRand Unified Bootloader, version 2 (PC/BIOS binaries)
ii  grub2-common                              1.99-21ubuntu3.7                                  GRand Unified Bootloader (common files for version 2)

So I'm thinking:

Code: [Select]

sudo apt-get install --reinstall grub-common grub-pc grub-pc-bin grub2-common

and possibly

Code: [Select]

sudo apt-get install grub-gfxpayload-list

then trying:

Code: [Select]

sudo update-grub

What do you reckon ?

.


Actually the DEBAIN control file for grub-pc states

Depends: debconf (>= 0.5) | debconf-2.0, grub-common, grub2-common (= 1.99-21ubuntu3.7), grub-pc-bin (= 1.99-21ubuntu3.7), ucf, grub-gfxpayload-lists

But the control for grub-common "suggests" os-prober too (which IS a default package

So this will probably do the trick

Code: [Select]

sudo apt-get install --reinstall grub-pc os-prober

the rest should be pulled in automagcally.

I am not having any problems I am offered mint and XP in the Grub list and they both boot normally.  I could always use Grub recovery disk if required.

[Mark Greaves (PCNetSpec)]

You WILL have problems if you ever get a kernel or grub update .. or ANYTHING else that needs to modify the boot configuration.

Point is .. do you want to fix it now, or then when we may not be about ?
