GPartedはGNU PartedのGTK+フロントエンドでありGNOMEの公式パーティションエディタです。さまざまなファイルフォーマットのパーティションの作成/削除/リサイズ/チェックに利用します。またパーティションのコピー・ペーストだけでなくドライブのボリュームラベルの管理にも使えます。GPartedはextraリポジトリで手に入ります。必要ならLive CDもあります。Live CDをダウンロードする理由はアンマウントしないとできない、ルートファイルシステムのパーティションの修正を行わなくてはならない場合などです。

Warning: GPartedはドライブパーティションの読み書きを行うので、不適切な利用はデータロスにつながりかねません。GPartedを使う前に影響を及ぼすパーティションをバックアップすることが推奨されています。


GPartedが対応しているファイルシステムの一覧は、GPartedのホームページのfeatures tableで見ることができます。

GParted Support

Have a look at the Official GParted Forums prior to executing a command if you are unsure about what you're doing.



See the Gparted-Live wiki article for instructions on adding GParted-live to your Grub menu so you can boot into the same live environment as the GParted-live CD directly from Grub and without the CD!

Windows XPとのデュアルブート

If you have a Windows XP partition that you would like to move from drive-to-drive that also happens to be your boot partition, you can do so easily with GParted and keep Windows happy simply by deleting the following registry key PRIOR to the partition move:


Reference to this little gem: here.

Fixing Messed-up Partition Order

Your partition order can get messed up if you have logical volumes and you erase one of them. Consider the following example:

/dev/sda1 (Primary partition)
/dev/sda2 (Primary partition)
/dev/sda3 (Primary partition)
/dev/sda4 (EXTENDED partition)
/dev/sda5 (Logical partition)
/dev/sda6 (Logical partition)
/dev/sda7 (Logical partition)

So 1-3 are primary partitions. 5-6 are logical partitions within the extended partition. Let's say you want to nuke /dev/sda5 and copy/paste /dev/sda2 into the resulting freespace. Now your drive looks like this:

/dev/sda1 (Primary partition)
/dev/sda2 (Primary partition)
/dev/sda3 (Primary partition)
/dev/sda4 (EXTENDED partition)
/dev/sda7 (Logical partition)
/dev/sda5 (Logical partition)
/dev/sda6 (Logical partition)

Notice that the order is messed up after your delete, copy/paste operation. This can cause all sorts of problems from not being able to mount an expected partition, to grub error 17/no bootable system. The solution to this little problem is simple:

  • Boot with your Arch Live CD or GParted Live CD (or any other live Linux CD)
  • Run fdisk on the drive, enter expert mode, fix the partition order, and write the changes to disk

Example using /dev/sda

# fdisk /dev/sda
  1. Once you're in fdisk, choose option x (extra functionality (experts only)) and enter.
  2. Then select f (fix partition order) and enter.
  3. Then select option w (write table to disk and exit), and enter.
Note: You must run partprobe (as root) or reboot the system in order for the kernel to read the new partition table!
