10.10: GParted Partition Editor

do the partitions occupy all the space on your hard drive?
if they do, you'll need to resize (shrink) them to make space for new partitions
you can only have a max of 3 primary partitions and 1 extended partition. however, you can make as many partitions as you want inside the extended partition

Yep, the partitions occupy all the space on my harddisk.

How can I shrink a partition? I don't have this entry in one of the menus.

Thanks a lot.

you cant change the partition if it is mounted. so easiest way would be to boot from a live cd -> start gparted -> mark the partition you want to change -> choose partition from menu -> choose resize/move

then you should be able to resize and create new partitions.

Thanks.

Ok, I boot from a Live CD. And then I have to choose a possibility, where I can decant commands.

I tried start gparted in a terminal and got the error: Unknown job: gparted. How can I start gparted in a terminal or in a command line?

Thanks.

Make sure your backups are up to date before manipulating the partitions

i guess you need to install it first.

you can do so by open up a terminal and type:

sudo apt-get install gparted

after that you can open it via terminal with the following command:

gksudo gparted

i don't know whether you really need sudo in a live environment. if this doesn't work try the same without sudo and gksudo.

@actionparsnip important hint :-)

Thanks for the hint. It runs with gksudo. So I guess, my problem has solved.
